I say do a sweep and get rid of inactive players and maps that have not been used in years. That might clear things up. Also, if people are willing to donate the money to get a new, bigger, faster, server I wouldn't back down from starting a donation box or somthing. Please, do something!!!! I want to be able to log on to the game when ever I feel stressed and decompress with my friends.
Maps are impossible to sweep because they are stored client-side (in the FH folder where the users put them). If the files were removed, then users would be complaining about an old map they loved being deleted from their FH. However, whenever there's a server restart, all map servers are removed and they return as people enter them. So, old, unused maps put no strain on the server because the maps' servers aren't there to slow things down. Just throwin' that in there.
As stated prior, money is not the issue. The game is pending an update from it's programmer and until we see the update there is little to be done.
I say it again, money is not the issue.
It's not THE issue, but it is an issue. The server costs money to run. Even if there was an update that did things like remove Fluorite Plains and add more maps, there would still be more strain on the server just from so many people being online at once. The only solution besides a mass-ban is a better server. A better server costs money. And thus, money is an issue.
