Under the new Hotmail system (apparently changed yesterday), I cannot add a contact to an existing group or otherwise manage groups.

The button for manage groups seems to allow only adding a new group or deleting an existing group.  I cannot find a way to edit an existing contact by adding or deleting contacts.

I know this question was supposedly answered, but the response was not helpful as it did not provide any useful info.

Many thanks to any of you smart folks out there who can figure this out.
