Well my knowledge of IRC is pretty basic but it's fairly simple with Trillian.
Get up the connection manager in trillian, make a new IRC connection. Choose Afternet from the list at the side and pick a server (There was only one when I tried).
Fill in the nickname and alt (as TrillianUser always is already being used) I have no idea what the username and user information fields do so I simply typed my nickname in again (it's always worked).
Click on create and connect to log on to the server. Then right click on the IRC button in the main trillain window to pull up the menu. Choose join channel and in the box that appears type f2s.
See you on there
