Groups are managed through user profiles. In order to create or modify a group you need to first log in to an account.
Once you have logged in, click the Profile tab at the top of the page.
Click the Groups item in the menu at the top.
At the bottom of the page click the Add Group button.
In the Add group page that loads, at a minimum you must enter an appropriate name in the Group name edit box.
You may also want to enter a brief description of what the group is for. Visibility can also be set.
Public visibility means that the group will be returned in group searches initiated by any registry user.
Private visibility means that the group will be returned only in searches initiated by group members or the owner. Note that a group owner is not by default a member of the group.
Click the Save group properties button. The group is added to the registry. A user transfer control is extended in the page. Now you can manage group membership.
