For those of you on LJ who want to comment to my posts: a primer on how to use OpenID

So, because I'm on DW these days, and want all my comments in the same place, comments are disabled on my LJ as you might have noticed.  So I occasionally get anonymous comments by people who don't have DWJs and want to comment.  But!  If you have an LJ, you actually can sign in using your LJ identity to DW, through a process called OpenID that LJ pioneered and also works at several different blogsites.  Using your OpenID you can't make posts, but you can store icons for use on DW, make comments, get notified through e-mail when people reply to your comments, and subscribe to people so that you get a DW reading page that's similar to an LJ friends page, if you have multiple people/communities on DW you want to follow.  The only thing you can't do is post entries.  Best of all, the whole system is pretty easy to set up and use.  So, here's how to use OpenID.
