How I can join the GC4? I think, I must write a PM to someone, right?
Yes, as it says in the contest thread, you are to PM Elderon (the Faction Overseer of Lenfald) with the subject "GC4 Signup" and he'll assign you a task.
OT: As I said in the Lenfald thread, this looks like a really promising start!
