wordpress?

[tielan]

So, in the course of setting up websites hither and yon, I seem to have managed to create three separate userids for three different websites.

I know I can add users to a website as subscribers or admins or stuff (although it seems to want new users and doesn't appear to allow for pre-existing ones) but I'm not sure if there's any way I can indicate to WP that these three users are actually the same person.

Or am I doomed to be stuck this way forever?
