I just gotta correct people. There are a lot more players than I see anyone mentioning. Most of the action in this game happens in 3SPN gametypes now. So if you're looking for people to play with, you can download 3SPN and have Freon, Team Arena Master and Arena master showing in the browser; though quite a few Freon/TAM servers run a mutator that makes the servers appear in the deathmatch part of the browser.
If you do throw an event and run a server, I would totally recommend my maps.
thanks.
