This message arrived in the Moodle.net inbox:
Hello. A few days ago I installed moodle on our school hosting server so we can start using it. I registered the moodle site and everything went ok. But then I accidentally did something and had to reinstall it completely. Now when I try to register again I get an error saying: "You are trying to register a site with a url that was previously used by another registered site. A request has already been sent to the site administrator of this other site." And the error is "error/local hub/freshmoodleregistrationerror2" The thing is that this has been since yesterday and I haven't gotten any email or anything to unregister my previos installation. The URL that we registered with is (*****removed by Mary) I would appreciate if you can help me with this issue so we can properly register our actual moodle installation.

I have checked with the reporter and their email is not in their junk/spam box. I also tried to locate the site via http://moodle.net/local/hub/admin/managesites.php but kept getting timed out.
