A group's member (example userN) after login in "myaccount" can see his groups;
Is possible hidden this? I want simple that only group's manager can see list groups and list members;

Others:
If the userN click on his group, if block members is activated, can to see the link at members
and so can see all the other users.

If I hidden the block, the link for to see the list member, there isn't more but by url the list is always visible.
There is some options for to make visible list members and groups only at the manager?
