The Phantom Group Invites-- who could they be?

I'm a person that like to clean out my connection requests and group invites on a regular basis. But gradually, as time has gone by I have built up a collection of group invites that cannot be accepted-- or denied. When I click on the icon there is a seemingly empty list. Yet the icon with the little "4" next to it haunts me. The ghosts of Gather. The invisible groups.

I have been tempted to ask Gather adminstrators to make them go away-- but what the use? They are likely to go away only to multiply, plant gremlins in my computer, make me feel their wrath. Why risk whatever dangers lie in upseting The Phantom Group Invites.

 I have decided it is best to welcome this growing ghostly family to the corner of my computer screen with open arms. Denying them would push them into obvlivion, accepting them would bury them in my pages of groups and make them difficult to find. Perhaps that is why they make their presense aware, yet never show their face. Who knows?

Don't worry little ghosts. You day has come. I will honor you.  Since there are four of you carved into my screen forever I shall name you Washington, Lincoln, Jefferson and Roosevelt, after the faces on Mt. Rushmore. Even as phantoms, you are solid in my heart.
