This link is to a Forgotten Realms resource for a private game. It provides a lot of basic knowledge regarding the realms. It has some "house rules" type diversions from the materials presented in Forgotten Realms modules and sourcebooks, but much like Wikipedia it is a good place to start and to develop ideas for further investigation.
