How do you go about asking someone for ownership of their domain?
brk: From looking at the current site, it seems "the organization" is one guy who never got any further than spending a saturday afternoon editing some html in notepad.I would argue that most "absolutely amazing ideas" can exist on any domain, so there is no "the domain" in this case.  There IS a domain currently registered that is probably more fitting to your idea than registering some iteration of "mydmnhsnvwls" or something.If I were you, I'd probably start running with your idea and implement whatever you're going to implement.  Petition the current owner of this domain to transfer it to you for a reasonable fee.  Since the current domain appears to be setup as some kind of track and field scholarship/fundraiser site, maybe you could make an offer for $xxx.yy and a donation of $xxxxx.yy some time in the future when you reach a goal of profitability or sales or whatever.  Appeal to what the current owner appeared to want to achieve, but never did.
