I can't update the information on my profile. There are question marks seperating the paragraphs in my 'About Me' section, and I've been trying to get rid of them, but can't. Aside from that, I also can't add any new banners into my 'Main' section.
As usual, first question... are you using Internet Explorer?
If so, you might want to switch to Firefox, since the site (generally) behaves better using that browser. I understand it has fewer problems with Chrome as well. Try that, also try deleting cookies and cache... some people have had good luck doing that as well. If you're still experiencing problems, let us know back here and we'll call in the BIG GUNS to help!
