As Tiff said lots of peeps know lots of peeps but a lot of that stems back to the RSBB etc....
I think one of the best things about a BB like this one tho is you don't actually have to KNOW people as everyone is so friendly anyway. I mean I have been done favours from peeps on here I ain't never met before, which in real life (

) wouldn't happen and that's what makes this place a great place to be
