Can You Set Expert Categories?

Team WPMU,

I'm trying to build a service directory on one of my sites for experts in my niche (publishing). I don't want to have a job listing -- just an expert listing.

In working with your plugin, I cant' see how to assign categories to experts (editor, artist, formatter, etc). I can see the skills area (which is really weird with the percentages -- what is that supposed to mean? Can you be half an editor?), but those items don't appear to be standard (I can't set them centrally), nor are they indexed -- searching for them doesn't yield much return.

How can I use this plugin to have a listing of experts that are searchable and divisible by category?

Thanks,
Rob

P.S. Tried doing this with the Directory plugin, but due to it's reliance on virtual pages over shortcodes it was unusable for my purposes.
