Hi Beleg. Welcome to Planet Tolkien.
There are two places within the site where your User Info is stored. Although one is for the site in general and the other is specifically for the forum, I'm afraid your changes have to be made in both places to be effective.
The first one is under [u] My Account[/u] on the menu bar on the left. In there you will find a section called [u] Change your Info[/u].
The second place is at the top of this section where it says Profile. If you change the information in both sections, it should work.
If this doesn't work, try sending an email or a PM to Taz explaining the problem. If it's due to a fault with your account, he's the only one who will be able to fix it.
Oh, and by the way... A word of warning.....
If on your travels you come across a geezer called Turin, make sure you don't have a sword handy when you try to wake him up :sad:
