I have about ten users out of 750 that have their usernames displayed in brackets on the Write Post screen. Does anyone know why this is?
All of these users are Contributors; some have been users for a really long time, some are new.
If I select their name as the author for a post, it shows in the post lists as having no author. However, when I view it actually in the blog, the author is set OK.
This is a fairly standard WP install which is integrated with BBPress.
