Hey RH, thanks your for input on this. Allow me to clarify a few of the points you brought up below:
laboRHEinz wrote:You assume speccers just sit there and do nothing but smoking/drinking/whatever because of their laziness. Well in fact, there are many speccers (including me) just waiting for a map they like. Still there are some players wanting to play classic maps only or others, waiting for a different kind of map like big-tank- or NV-maps. Some prefer speccing rather than playing a map they don't like and therefor, the accu-mode is quite handy and helpful

[...]
For the record, I don't have a problem with speccers speccing. In fact, I'm quite delighted that CEONSS allows as many ppl to spec as it does since the drawback of taxing the server's BW by a certain amount is both offset by the fact that the connection seems to be very fast AND reliable (currently

) as well as by the positive effect of keeping prospective players around anxiously anticipating the next match where they'll be able to join; it's sort of like extra advertisement for the server, to put it coarsely. So while speccers are and should always be welcome and respected, the benefits afforded to them, I think, shouldn't extend the spectacle they get to enjoy to include free extra votes for later on. Voting power is a reward for actively participating in a match, thereby boosting the network effect and thus the server's current worth compared to other choices, and this reward is granted no matter if you voted for the map played or if you were in the minority that didn't get their way. Especially in the latter case, by sucking it up and playing an unappealing map instead of taking off like a spoiled kid who didn't get his way, you prove you earn your next vote and the goodwill of others who might be more inclined to do the same for your map choice next round. That's how friendly communities are built, after all. By granting speccers vote accumulation, you kind of drive a stake through that process and implicitly you're just telling ppl, "hey, if you don't like the coming map, you can always sit it out and you STILL get enhanced voting should you decide to join in on the last second before a core blows just to revote. Neat, huh?". This is not a message I believe we should be sending and that's why I'm in favour of modding action towards disabling speccer vote accumulation.

He'd have to wait about 5-10 maps to completely override others votes. Now this will happen every 1-2 hours which is not a big problem IMO. Besides, there should'nt be a totally crap map on the server and if so, it has to be discussed somewhere else

Thus, even when a player tries to abuse this voting mode, there'll appear just another nice map to be played.[...]
I won't name names, but I have seen several 7V-8V bombs dropped at the later stages of some late evening map votings glaringly overturning seemingly decided outcomes and typically by some ppl who frequent the spec seats. Certainly nothing as big as 10V or 15V strong (who'd have the patience to spec that long while dodging the constant 2min idle kick checks after all? umm, we DO have idle kicking enabled, right?), but still, enough to reverse quite obvious majority choices by a healthy margin. As to whether that was for the best or not map-wise, that's entirely subjective and I won't get into it for obvious reasons (convincing/educating ppl to improve their standards leaves a much better taste than forcing "better" map choices on 'em). As an admin, however, I'm sure you'll appreciate the problem of having a big(ish) group of ppl feeling frustrated that their voting privilege was trampled on right after they exercised it, just as the map is about to turn and the F10 key (or server browser button) is so conveniently within reach. Now, whether the frequency of such a phenomenon is every 2, 3 or 5 hours isn't very important as it only needs to happen once per average player to give 'em a good enough excuse to hop servers (the dreaded server-clearing map effect). That's why I'm arguing for a max votes cap and a "full disclosure" clause where either the total voting power will be displayed on a modded voting panel ("Players: 25, Total votes: 36" for example) or the stronger voters will be forced to "show their hand" early so the rest can make an informed decision right after that.

Aside from the reasons I've already argued for, continued slight server improvements through (tested and approved) mutators/serveractors is a sign of constant interest in maintaining quality that players will appreciate and recall when making their nightly server choices. I know it sounds an awful lot like marketing lingo, but it's the truth; personally I feel much better playing at CEONSS knowing that cool things like hitsounds and voting tweaks have recently been added and more are likely to follow that'll improve my ONS experience even more than other more stagnant servers left to their own, 7-year old devices.
Btw, for more interesting ideas on further server service customizations (sounds silly and borderline redundant saying "server service" but I honestly dunno how else to phrase this :/), look no further than the swiss LDG mixed gametype server: modded voting panel to include map pics (alas, no map description upon image mouse rollover or further info on the specifics of weighted voting dynamically and on the same panel), F12 extended server news menu mutator allowing for much more ingame info offering freedom than the MOTD 4-liner, brightskins (although that one is a problem in its typical UTcomp form with ONSPlus), and more. These guys get it; they may play silly maps and gametypes, but they still
get it.

One major disadvantage of the 1-score-vote-mode is that only the commonly known and super-popular maps will be voted over and over again. The lesser known but still nice maps will rarely have a chance to be played. The accu-mode helps a little bit here.[...]
I think most ppl are well aware of the maps they like by now no matter where their relative position on the map list is. They sometimes sort by ascending played times to identify new entries but, overall, I doubt a different voting method has anything to do with map discovery. That is (and has always been) a screen real estate problem with UT's voting menu IMO.
Thanks for everyone's comments on this.
