Anyone know how to create a new category…

automatically upon new user signup? The category name would be the username that the person signs up for. Basically I’m using wordpress as a CMS, using the role manager plugin and several php tweeks I’ve done myself.

I run a music website, want-signed.com and if someone signs up for a music artist account I have to do several things to set it up before they can start posting/ uploading. I’m working on automating the entire process, so any help with this aspect(auto-creating a new category) would be appreciated.
