Did you see the the Wiki link on the top menu bar of the forum? A lot info about the game can be found there.
If you know the game already: help in writing the wiki is appreciated. In order to help writing, register there. The wiki account is separated from gewar account. Nevertheless it's helpful to use the same name like here.
But: I saw that you confuse the password manager of firefox if you use your gewar name but another password, it just uses the URL www.gewar.net and ignores the /wiki part so either use same passwords for game and wiki or slightly vary your name when registering.
