OpenID

I've had about a billion people to ask me to enable OpenID on my blog. The only way I can enable OpenID is to also allow anonymous postings (!!) and when I do that I get 50+ spam a day to sort through. I think it's LJ just being difficult. Ideally I want to move away from LiveJournal as I have the free account that is getting more stupid every month and the spam problem is getting worse, even just allowing registered users. Does anyone know how I apply for a blog at blogs.gnome.org? I've tried, but Sorry, that email address is not allowed so I'm guessing I need a @gnome.org email address. Any other ideas?
