I believe you are referring to the server plug-in we run known as FinalBattleGround.
Please proceed to
www.finalbattleground.com and make an account. It will ask you for your steamID. A steamID can be found by opening up console and typing in "status"(Without the quotations"). A list of names will appear, find yours and copy the steamID beside it.
A steamID looks like: STEAM_X:X:XXXXXX
Once you make your account on finalbattleground you're going to want to find a verification code somewhere on your finalbattleground profile. It should look like "!verify 123". The numbers change from player to player.
After copying down that code, you're going to want to enter our servers and type it into chat. It should then verify your account, and link your ingame stats.
Please tell us if this is your issue or not. Thanks.
Additionally, we have a CS:S discussion section located here:

Also, we have a FinalBattleGround forum located here:

EDIT: Aw, all that typing for nothing. Oh well.
Oh, and I suppose this can be locked now...
