joined dates incorrect in search by username

[allisolm]

Here's a minor glitch I haven't seen reported - doesn't mean it HASN"T been reported, just that I haven't seen it.

search for posts by allisolm, all categories, display results as messages, 06/10/2007 - 06/14/2007. Check the joined dates.

At least that's what shows for me with IE6. I get the same type of results with other user names.
