Topic: Gamemode: MOD
Modded servers have gotten so common nowdays that if you just join a server casually it is very often a modded one. Personally I find this a bit troublesome. I don't mind the existance of mods, and they can be nice to play, but it's still annoying to join one by accident when wanting to play a normal game.
Therefore I suggest that you make it so all modded server register as gamemode MOD in the serverbrowser. So if it sais DM, TDM or CTF you would know it's a normal server, while if it sais MOD you can read the servername for hints of what it is. I'm thinking the browser could handle it exactly like the other gamemodes, so you can filter them out, filter so you only see modded servers and so on.
