Star Trek discussion

I have belonged to Paperbackswap.com now for years...I get most of my used ST novels on there....And when my husband has finished with a novel (I read it first; he is very slow) I put them up for trade. I may have to wait, but it's been useful....Not as good as it was before they instituted membership fees. But, I still think it's worth the $12. Sad to see how few new novels are on the shelves at bookstores.
