@Asse: No, I didn't want to make a secret out of it. Aum has its own tread at the forum now - it's all in there. I don't plan to release an online version of the magazine, at least not in the near future. You can use any texture pack, as long as it can be distributed freely.
@Bilbo_Bogimps: I didn't use helpscribble - its user interface is a bit outdated in my opinion. The chm file is compiled using the html help compiler.
