There's always the option, if a guest wants to rant, of using
E-MAIL THE ADMINISTRATORS
at the bottom of the forum page.
Seeing how bumpy "Mind Numbing Stupidity" was this morning--it got really bumpy--and seeing how the administrators had to run around for about three weeks, scrambling to nab trolls, this could make it more difficult.
I guess it sounds like an interesting idea, but I'm looking at the "management" part of it.
