7.0 has just had a reorganisation due to the MTR merger.
The official site IS www.totalrealism.net
forums= forums.totalrealism.net
www.rometotalrealism.org is the old site.

Check out RTR PE for 1.5 its the newest semi official version (its basicly gold on 1.5 but 1.5 is much better so worth checking out). A few other mods also incorperate BI features in the meen time.
