Per GLEP67, the project e-mail address serves as purpose of identification. Reusing the developer e-mail for project contact can't work then. Please let me know what you'd prefer to do: 1. get a new alias for the project, 2. remove the project. For the former, just leave a comment and I'll create it. For the latter, you can remove the project wiki page yourself.
I'd say lets go with installer@gentoo.org if that's possible.
Alias created, bugzie account too. Now please update the wiki.
