The swapping actually occurs on the swap thread

How it works:
1. You see something in the current offer you want and you post "mine". Then go back and edit that post to include your offer and pm the person you claimed from with your address. . (We do it this way because only the first person to post mine gets that person's item. The swap you claimed is shipped to you. Somebody then claims one of your items by saying mine. They then pm you with their address and you ship the item to them within a few days unless you state in your offer that it will be longer.
If you miss something you cannot live without, pm that person and see if they want to swap for something you have.
We try to keep all chatting on this thread and all swaps on the swap thread linked above. If you have any more questions, just shout. This group is wonderful.
