It's come to my attention that several users seem to have lost their usename, it's not showing up in their posts or in the site's database. I've sent e-mails to all of the users concerned but if you're one of them and haven't received an e-mail please get in touch with the council (firstname.lastname@example.org). We apologise for the inconvenience.
A while back i wrote some code into the user profile (http://www.planet-tolkien.com/update_profile/) that would allow users to change their username and e-mail, when i updated the live site with the code i removed the ability to change the username from the web page itself but not the update profile process. Recently when somone changed their profile, there being no username shown on screen the update file simly erased the username.
I've fixed it now - to get your username back go to update profile and write in your username and you're away.
