We NEED more participants though - jump on in guys!
I count 11 who have put their hands up. At an average of 2 weeks (usage and postage time), that is ~ 5 months for the box to go around. As you know from previous experience there is always someone who sits on it for a month, so make that closer to 6 months. Reviews and discussion will bring more out of the woodwork so you may as well start it.
