Ive had an idea for users to have there own home pages, no guestbooks or anything, but just things like a Personal Motto for selling e.g I always post withing 5 days or My items are never used or always as seen in the photo. A database of all there swaps which they can choose to show. Things theyre bidding on.
Wishlist And maybe selling theme as some users only sell a certain type of thing e.g Swapits_Beauty would have a Style or Beauty theme.
