Hi Pat
You have to click on "User CP" (user control panel) option and then "Settings & Options" - for the signature to put all your gear in just edit the "Edit Signature" section - everything you want the world to see can be edited in the User CP
Just be careful about posting too much expensive gears, I might pay you a visit and "pick" them up when you're not home,
!! Nah, just a bit of tongue-in-cheek
HTH
Cheers
Bill
