Claim your LJ OpenID on Dreamwidth!

Before you abandon LJ altogether, or even if you don't intend to leave at all, go over to your Dreamwidth account and claim your LiveJournal OpenID (see instructions here)

Doing that ensures that all the comments you made over on LiveJournal will link to your Dreamwidth account when people import them. And if you haven't imported your LJ yet, do it soon before LJ notices that it's going on and blocks it.
