We do this over at Predatormaster.com, and they call it a "Pay it Forward" forum. Only for established members, and you have to offer something up if you claim something.

Which reminds me, I paid mine forward about a year or so ago, but haven't claimed anything. I handed off a custom Single Six holster and 75rnds of 32H&R that I wasn't gonna shoot, still haven't figured out what I'm left needing.
