It always annoyed me that the one major place I didn't have the user name of 'ChristopherA' was LiveJournal, in particular as the user with that ID never used it.

Well, LiveJournal now offers a rename service, where for $15 they'll rename your old account and redirect all your old friends and traffic to the new name. Also, the old defunct user's account is moved as well, it is now at http://ex-christoph388.livejournal.com/profile , which has nothing in it.

So my official LiveJournal URL is http://christophera.livejournal.com
