Discovered some bugs involving registration of users who have been invited to projects that were deleted before their account has been made. See trac bugs #2243, #2262, and #2263 and possibly related #1149. For an easier (graphical!) walkthrough on how these tickets are related, see...

Also, there's a weird display quirk on the Epiphany browser. See http://www.openplans.org/projects/operations/mchua-2-14-08-deletion-while-invited/epiphany-firefox.png - epiphany on left, firefox 2 on the right.
