[BluffTHIS!]

But a PM doesn't allow for the fact that many posters might share another's views and have an interest in seeing certain moderating decisions discussed. Plus this would put all such discussions in one out of the way place so that such gripes don't hijack other threads. Note that an alternate way is a sticky "Flame the Moderator" thread in each separate forum. When it gets so long, just lock it and roll it down and start a new sticky.
