Firstly, welcome to our server.
You will often read on these forums about the custom channel glff. This is just to warn you, the main channel for Evernight is GlobalLFF, not glff.
To join this channel, you simply have to type "/joinchannel GlobalLFF" (without the quotes) into your chat box and press enter. Then type "/1" and press space to select the channel to type in it.
Similarly, there is the GlobalRookie channel, created specifically to help new players learn the game. To join this channel, follow the same steps as above, but use GlobalRookie instead of GlobalLFF.
If you get stuck, send me a message ingame to Anionwulf or Swiflo, or send me a PM on these forums.
Hope to see you around!
