I'm newbie on the Zope development.
I'm creating a site using Zope + Plone. The site will have several new roles because there will be some folders only accessible for some users. So I need to give them a different role when they fill in a specified form and is sent to the server.
What I want to do is when they fill in there profile and submit it they get added to a new group "Mentor" .
Does anybody has any idea of how I can do this?
