I will make a thread on the official Steam group and I will post some easy to follow instructions accompanied with the command list. Which will be linked to !man.
TerywjPerhaps a instructional on how to use IRC and all that would help the newer guys.
I recommend people who wants to use IRC to connect from http://atf2.org/
As for adding #tf2mix on atf2.org then it's already there, for the people who don't see the channel it's due to the favorites you guys already have. If you already connected to atf2.org then you already have favorites saved in your browser cookies. I do not force remove or force add any of your channels. You can fix that issue by doing what #24 said or by deleting your cookies for this site (or all your cookies). I recommend typing /j #tf2mix
