I got an email from DVDSwap today that said, among other things

"Thanks to each and every member who participated in our February Promotion at SwapaDVD. Our next promotion will be coming soon to one of our sister sites, PaperbackSwap.com. If you're not a member there already, join now! You'll definitely not want to miss out on our next contest!"

What kind of promotion or contest are they talking about?  The one on DVDSwap was extra credits for postuing 10 DVDs.  I just got an influx of books and would hate to post them all and then get an email or notice for a bonus!

Thanks for any input you might have :) 

I believe it's going to be a guessing contest for the 2.5 million books mark.  You get three guesses and the closest guess wins credits.  They had a similar promotion for 1 million books.

Thanks a bunch for the info!
