I have to agree with Vodin on this. The site is your baby. If you need the funds and selling it will help go for it. I'd hate to see it go away, but would fully understand.
Like Vodin and Keepist requested, Let us know whats gonna happen and if you you do sell PLEASE pull all personal data from it.
The only other thing I could think of would be if you could give us a few days notice to contact other so we can remain in touch.

EITHER was, I want to THANK you for all you've done in putting this site up and maintaining it for everyone.
