What can I do with my failed portal?

About five years ago, I had started a classifieds portal (sixteen2sixty.com) for the Indian market. I was naive in my execution and it didn't eventually go anywhere.

I have 8000+ people signed up on it, and people are still posting some stuff on it.

About 900 visits a month. Can I sell it for something useful? The domain (I know not!) or anything else?

Thanks guys... Raj
