OFC it is, but it's infintely cheaper in terms of development and less rigid than, for example, some text on how to make implants from an in-game book. IMO, some of the player information assembled in these forums is way more detailed and useful than anything FC could put ingame, one reason being format. It's also relevant to say you would have to know where to find the information ingame to benefit from it. Advertising the AO forums ingame is easy .... billboards, global messaging system, the greeters. They could implement a free items booth that gives you some piece of junk item to sell for 100 creds and spams you with a message ...
