There have been recent major changes to the way that Facebook allows the administrator to manage group pages. These changes took place without warning and now make it untenable to control content and members.
Facebook make it extremely difficult to to delete a group. For one thing, they don’t tell you how. After much time searching I finally found how to do it. After 1000 clicks I finally managed, so now there is no Milton Abbas Local History Group Facebook page. Any group with say more than 1000 members would be almost impossible to delete.
Apologies to the 143 members who had joined.
