Official #tf2mix Steam group
Have fun, PUG hard, play nice.
How to play: use an IRC client and join the channel #tf2mix on the Gamesurge network. If you do not have a client you can use the website http://atf2.org/ It can happen that you already have favorites with this website, if you do not see #tf2mix in your channel list you can join it by typing: /j #tf2mix
You will be required to join Mumble in order to play these PUGs. Mumble is a voice chat program. You can download it there: http://downloads.sourceforge.net/project/mumble/Mumble/1.2.2/Mumble-1.2.2.exe Once you have it installed you will need to add our server. The informations are: address mumble.atf2.org & port 64738
Once you are done with the Mumble installation and you are online on #tf2mix you just need to type (or whatever class you want to play): !add scout
