Different user types?

[michaelbang]

I run a photographer community, and I'm concidering to open up for models as well. But is there a mod (or default product) that allows new users to pick between different user types? E.g. "Model" and "Photographer"? And do so that the choice is viewable to other members of the forum, and maybe give them different permissions?

I know it can be done manual, but I would like the users to do it themselves.

Possible??

Thanks.
