After reading most of these posts, I'll reiterate my opinion, along with some of the great ideas I have seen.
It seems a vote, in one form or another, is the popular choice here. After leadership switched back to dust just now, it has been pretty popular, but we all know that won't last.
I say we have monthly votes on the forums. Maybe even on the server, if that's practical and possible.
An example:
"The map is currently: de_dust.
What map would you like to play next month?
1. de_aztec
2. de_compound
3. de_nuke
4. Keep it the same!"
5. I do not play on that server so my vote is neutral."
This could be a sticky in our division forums, IMHO. The server could have an automated message informing players and eGO members alike of the vote on that server, which could also increase forum traffic and allow us to gain more members in the process. Win-win.
I think this is the smartest way of going about it. The server may gain popularity by those who dislike dust but like aztec, or other classic maps (like me). It will also retain those faithful who have played on dust for ages. And, if for any reason the trend changes, it allows for new favorites to be found, if any.
If the server on the whole is still dead, then we can easily tell this by the lack of votes and traffic. It will be clear that it has become, simply, an obsolete server.
Whatever we ultimately do, the looming release of CS:GO will null and void it, anyway. But I just want to have fun in the meantime!
Thanks for reading.
