With regard to moderation, it is mostly good here on PPRuNe, but occasionally appallingly bad.
I found myself banned recently, apparently for the appalling sin of arguing a point. Whoever did it didn't give me a reasonable explanation, and didn't have the courtesy to identify themselves. There was no warning given, and no attempt to edit the offending (??) posts. The other party to the argument, who had been quite insulting, was left alone as far as I can tell.
Now I don't really care much about the ban - gave me a chance to do some work on the house instead of PPRuNing - however, the manner in which it was done was quite appalling, so much so that I suspect it was personal.
My only plea, therefore, is that if this new forum was to go ahead (and it is a very good idea), that the moderation would meet the same standards of professionalism that we exercise in our duties as pilots, ATCOs or engineers.
