"Sometimes I just don't know what to do."
Robert, I think you've been very good at knowing what to do.
It cannot be easy, with so many different personalities.
The situation with the meanness that was directed toward the Vacuumland member seems to have been going on for a long time (I'm assuming this is a continuation of that).
You've impressed me with your calm resolve, your humor, and most of all, your consistency to speak out against what you see is an injustice against a friend, and, really, this site's "sister site and best friend", as Vacuumland is billed at aw.org's introductory page.
You're doing quite well, I think.
