I consider this a legitimate suggestion.
The link to the left takes you to #twhl, a room obviously reserved for mapping talk. There IS another channel called #twhlregs.
The site designers, in my opinion, should change that link to go to the regs room, and info should be put in the subject of that
"If anyone has mapping questions, we would like it if you join #twhl and ask your questions in there"
I believe this would save a lot of headaches.
Also you may want to put in THAT room's subject that occupants may not answer due to mapping or other activity.
