I bet it's just some obscure phbb permissions setting that would need to be changed.. the kind of stuff Uber Elf Gangolf could figure out in his sleep

Oops, sorry, looks like it's my thread that got moved like that...

But hang on, all that has to happen is for somebody with a fixed web page to link to an Off-Route forum page, and then Google has a way back in to index.

Sounds like a new entry in the robots.txt file should do the trick.
