I don't know if it's just the Domain name they are seeking. You can do a search on what domain names are going for and most deaf related domains are under 5 grand. 500,000.00 is quite a bit to pay for just the domain name. It would be interesting to know what their plans for the site are and if they agree to keep it going, that should be in the contract somewhere. Otherwise they can just say they wil and then kill it or revamp it at their whim. If I were you Alex, I would take the money and run. You can always start another site like this one and let us know where it's at. I'm quite sure most of us would go there. You could also negotiate the content in the deal so you can move it to the new site if you decide to go that route.
