okay. i looked for this in the forums, and all i found out was that possibly my firewall or antivirus software was inhibiting my category-creating.  i turned both off.  i still cannot add friends to the categories i've created. any other suggestions or ideas? 

I'm having the same problem.  Have tried other browsers, clearing all cache, etc.

I want make my back ground

 If it makes you feel any better I am having the same problem.... When I try to add people to categories it just says loading... I even tried leaving it for an hour just to see if it was slow... Nada

 I also tried IE just in case it was a problem with Myspace and Firefox but no love :(
