The rules are:
1) No charis. Standing only.
2) Huddle means everyone must sand in a circle. No pass-outs.
3) No minutes may be taken.
4) No laptops, drinks or mobile phones.
The Seated Huddle and Talk is the more frequent (and less productive) cousin.
Any SHAT must have a Concise and Unambiguous Note Taker.
"No, let's have a CHAT."
