Profile help?

Ok, I've been joined to this site for a while, then haven't had too much time to come back on, and they changed everything. I try to edit my profile, I took out all the funky letter things, slashes, dashes, underscores, brackets, everything. But it still says only letters and numbers may include your profile.

What do I need to take out? :S

Hun,it means you shouldn't have any funky things in your nickname too..
Hope this helps
Sincerely,
Laura

No yrene hun,it's about her nickname...It isn't allowed to have this funky things if she wants to edit her profile
