I'm not a member of FABO or FBBO, but I have looked on there a few times and recognize numerous people who used to be on here years ago. Some people bounce around between sites, and some have just picked out one they prefer and stay there.

The for sale section here has burned me a few times many years ago. Be wary of the people who you don't recognize who only use the site for the free ads just like you would someone on Ebay with no feedback or bad feedback. Wish this site had a feedback rating like others do. Eventually the bad guys get identified and ran off.
