Hello dear drupal expert!
Trying to find a good solution for segmenting my site (taxonomy, user control..) I often come back to what I had expected drupal to work like - but never found the feature of my dreams: and that is an access control based on the username-access-rules.
I would like to build an easy user-registration that automatically divides the registrants into categories, without the need of pointing them to a specific role by hand afterwards. And because I want the registrant's dedication to one group be visible in the username itself it would make sense to build the site's segmentation up on username (or e-mail/ip) access rules.
So the usernames would look like e.g. (this is possible now with acess rules)
A-username1, A-username2, A-username3
B-username1, B-username2, B-username3
C-usern....
But what I miss is that I can define different Access-control for the groups A-%, B-% and C%.
Maybe I only didn't find how to do it. But 'access-rules' just naturally evoke the idea in my head that there should also be the possibility to DO something with these rules... And it would be nice :-) Maybe my idea isn't realistic at all (lacking of PHP knowledge) and maybe it's also not useful for drupal. But in my case it would be, I'm pritty sure.
