@Chip Bennett - Totally understandable, and it is a shame that the power of few (spammer) are controlling what we can do, but that's true. If we open it to email registrations it would become a spam fest in days.

@Luis ManageWP.org also offers free service that we want to become open source as well. I do not see why it needs to necessarily offer the same service offered by .com (Wordpress did not make that standard, its just the way it is). I felt ManageWP.org sounded good too, and would not mind calling this service in such way even if there was no ManageWP.com. Service on .org still help you manage your sites in a way (improve them etc) so ManageWP.org seems reasonable as well. And I wouldn't mind wpengine.org magazine but I guess they wanted to distance their brand more.
