ok why do you need to put an ip in? You can either use xFire to Join Game of another in the server or use the in-game browser and find the server named along the lines of GSA-XGN FEAR TOG|Training or something very similar. If the pass is the same as last week (this is set by the XGN admin not me) then it will be 'togrocks'
Anyway check the XGN info sticky and in there you will find the Teamspeak details as well as everything else you need. Sorry its so big, but I was asked to Merge some of the stickies as there were way too many.
Be good to see you there Purplex.
