Or am I dreaming and they were not really here?
One disappeared - but it was slating chatroom manners so it doesn't surprise me.
Its always been the way, some threads get moved into the Mods Lounge when they need to be, some make it back and some don't.
I'd have to say that its for a good reason in the majority of cases, when its not they get put back pretty quick and it works out best for the site on balance.
I made a joking thread on chatroom speak / manners...
it was moved to chatroom. Not deleted. If thats the one you mean
