I got a PM from a member telling me they have traded with me in the past and would I like to trade again.  I am a boxer  (I have it on hold right now)

so I thought they were talking  BOB. I  told her we could work something out,  is she a boxer?  She PMed me back and said no.   I am sure I have

read somewhere that this against the rules but I can't find it. Can someone help me?  I would like to let this person  and anyone else that doesn't

know that it is against the rules. They may even read it for themselves as they post often on here. Thanks in advance for your help

Yeah it is against the rules. How about sending her this info from the help center-

Can we swap books for books directly with other members on this site?

Yes, but only if you both subscribe to Box-O-Books.

• "Creditless" swaps are permitted ONLY between two Boxers.

• Using the PBS site to conduct an under-the-table book-for-book swap without using credits would be in direct violation of PBS policy, and would put both members' PBS accounts in jeopardy.

Why is this?

• We have worked very hard on this site, and it has cost us (and continues to cost us) a great deal of money. The Box-O-Books service is one of the few sources of income the site has generated to offset our financial losses, and we are still deeply in the red. Without some financial support we will not be able to continue the club. We are trying to keep the site free for our members, and Box-O-Books was one innovation intended to help us do so.

• PBS relies greatly on the "honor" system among our members. We are pleased to say that the majority of PBSers are honest and above-board; if that were not so, the club could not continue.

• We hope that the rule makes sense to you, and that you understand that we are not being unfair or greedy. It is simply that if enough members did this, we would have to close down the club.

However, it is possible for two people to quickly trade books with each other for credits.

You only need one credit between the two of you.   The  first person  requests a book from the second person, that person marks it sent (even though they haven't yet), the first person marks it received (even though they haven't yet).  The second person now requests a book with their new credit, the first person marks it sent, etc.  So the credit goes back and forth faster then a tennis ball at Wimbledon. 

When all done, each party packages up the books and mails them off.
