If you're just moving in to DreamWidth...

Another step you may want to do besides importing your LJ is claiming your OpenID. Right now your comments on entries other people import will be showing up under your OpenID, but if you claim it they'll act just as if you posted them here, with icons if you're using the same keywords, with the ability to delete the comments, etc.
