Well it is included in the "admin panel" but what i mean is a user frontend.
Something that end up like (Just the get the idea)
http://association.drupal.org/about/staffYou can have a button called: "Add Group" (Which makes a group section, like Management, Admins ect.)
Next to that you can have a button called: "Add Group Member" Which gives the options for:
-Member Select
-Personal Contact details
-Function (job)
-Some other information
ect. ect.
You could put this information into a nice table with all the members functions sorted.
This way you dont need to create the page manually. Adding members / groups / functions ect. would be a lot easier.
Well, just like that website as an example.
