Indeed he does use ICQ for I have seen him on his "un"-well known number in the past week several times, although you have to be on at weird times of the night. I swear to god Stefan and Unixmad must have the most messed up sleeping patterns...
However you will not get his ICQ unless you really have something you need to talk to him about, that is why both Nemesis and I have his ICQ. Hahahaha, you only get it if you be important. jk. However if you reall yneed something read the support center forum, I believe you can get any realizeic quiestions about the game answered there, however they don't answer questions like, "Can I have Global RC?" there, so don't try it.
I only got his ICQ when I was thinking of making the new GuildCP, so once you have something like that to talk about, try back.
