I've had one sale for .60 since joining in October of '07.  The biggest problem I'm having at this point is getting the balance of my portfolio reviewed.  I have well over 200 photos that have been sitting in review since the beginning.  I contacted them in mid-December and they got back to me pretty quickly, and advised that I had uploaded my photos prior to a server upgrade and that everything had to be moved manually, causing the delay in review.  Unfortunately, I'm still waiting for them to be reviewed, and it's been nearly three months.
