Thank you for the terrific welcome, everyone.
I have certainly observed, from previous posts, Tom Watson's knack for getting hold of, and selling R9s. By all accounts he is a pleasure to deal with and I'll definitely keep that in mind.

That's a great question, and one I don't have the answer to at the moment. Even if a user deletes a received PM, it may still exist in the sender's outbox. As for if/when complete deletion takes place, I really don't know. There are several directions the YABB team could have taken and all have their pros and cons. It's worth checking out, though.
