Done as per my above message.
I have moved kitchen equipment threads to Kitchen/Health&Safety, PA stuff to Sound, misc building stuff to Building.
I have kept everything related to computers/internet and to miscellaneous technology that didn't seem to fit anywhere else.
We still have a lot of stuff here about projectors / DVD players etc. which are really events space equipment and don't belong under the AFWG. Should these go to Events, or should I expand Sound, or Film, or should I make a new category under Cafe & Events WG for this?
