Hello Dee,
thanks for getting back to me so fast. With my first question I meant, if the Profile itself (the questions asked by the system) can be changed (so in the course of the day you realize that you forgot to ask the students for their pet's name, that this is editable from the administrator instead of the developer).
If you want the multiple profiles, you might want to check out the user register we are going to upload within the next two weeks as this already supports multiple profiles which you could (with a little bit of additional development) link up to e.g. the signup process for a class. Though it does not include the fine grained permissions.
When you launched your RFC last year, two clients of ours had roughly the same idea, so we tried to make a generic package out of it, that could be amended in an easy way for all situations. I never go around to aggregate all the specs, but maybe I'll manage in the near future. The basic underlying idea is to have a package, that allows you to keep profiles (registers) of your users. At the moment we go so far as to say, you can enter the profile process using a URL and give it a return_url where users will be redirected to after they finished the registration. As a specific demand by GPI we added the ability to link registers to mailinglists which will sign up users for specific mailinglists. But you can imagine an easy interface that would allow you to signup users to forums or classes (e.g. if a new student enters MIT, he chooses a default curriculum, answers the questions of the default register (the thing that collects the profile data), and is subscribed to multiple classes. If the class has an additional register, the student will be redirected to fill out that register as well, otherwise he would be a pending student.).
Gotta run, more maybe later ;)
