Stick around, get the post count up, work within the rules. That shows character in most cases to me. Now in this case it sounds like he lost his old account, if that could be collaborated then I could understand maybe letting him sell but then that would open a slippery slope for others coming in and saying "Well you let him, why not me?" which could open all kinds of problems.
I hope you stay, nobody wants you to go, just work within the rules. I have lost accounts before, it is a serious drag and I feel for you, I truly do, especially since you are trying to sell. I would rather error on the side of caution though. I wish you the best of luck both in your sales and in the upcoming season.

You thought of me, I knew you loved me! Does that mean I will be getting a birthday card next year? You forgot about me in January you know and I was so looking forward to it.
