example that I want to do:
how admin I create 2 users AA and BB.
everyone can to create own users but cannot see the others users.
so AA cannot see BB's users.
AA (and/or BB) can to create and manage own private(no public) Vocabulary with some terms for example:
AA can also decide which users can access at terms:
-term1 is accessible only by u1;
-term2 is accessible only by u1, u2;
-term3 is accessible only by u3, u4;
I tested some modules but or the access permission isn't limited at own area (AA must see only own users) or isn't possible assign users at specific terms (not at all Vocabulary)
other: Vocabulary and its terms must appear in menu only for logged users with have permission for to see its terms.
other: AA (and or BB) when delete user those user must to be deleted totally, not remain in drupal users's list (list is here admin/user/user)
I think isn't necessary to create a new module but some tips for a good setting of some already existing. Is necessary yoa are very xpert indrupal; also I must tested your example site first of payment.
for others clarifications ask me.
small notice: range bid is automatically insert by site when I set small project (so think my proposal is a range more restrict9
