I provided this information in posts above. What more can I say.
Conaway, the first person to run the site, is probably the one who registered the domain name, but I suppose we will never know for sure. I do now recall him saying emphatically that it was his project, but Alcor approved of what he was doing. The heavy involvement of Brian Wowk, an Alcor board member, on the forum, could be viewed as some level of unofficial support by Alcor. That Alcor mentions the site in their newsletter can be similarly viewed but to me it is mainly an informational piece. None of this demonstrates that AU had official Alcor sponsorship much less ownership.
