Yeah its a VERY big forum. I have had one or 2 sour deals on there. You can look at the forum and see its lots of young people on there (whom alot seem to have an attitude, i call it the pinkbike attitude - its a real condition)
So as i said, no paypal gift on there and try and avoid trades unless you meet up or you have the item first (which doesnt really happen 'you send yours first' - 'no, you')
