WHAT IS A SWAP SUGGESTION?
Once you see a book you’re interested in, the next thing to do would be to suggest a swap. This is where you offer the owner of the book you'd like, one of your books in exchange. Once the swap has been suggested, the other member will be able to browse the books you've added to the system to find a book they might be interested in.
If they don't find a book amongst yours then they will reject your offer. If they do however they will then pass the suggestion back to you by suggesting one of your books for their book. Once that happens all you have to do is confirm the swap and hey presto, swaps completed and all that is left is posting the books to one another.
Please note though, you can only make swap suggestions if you're a member and you have books available on the system.
