We're talking about re-using domain name if I'm correct? The topic of branding was brought up by someone else, I expanded on it.
To really answer, I'd need to know the domain name. But assuming it is nothing close to a directory name, I probably wouldn't bother submitting even if it were free. To me, it is very amateurish. Most of these types of site disappear quickly, and lots of people know that. So, I think it would be very difficult to attract submissions. But again, without a specific domain name, it's hard to say. /*tom*/
