I'm pretty sure we *did* have all those rules, though except I think the limit was 2 weeks, and it made no difference. People just didn't.
I don't think we ever put a limit on the time we had it. I was struggling to find a time when I was well enough to sit up, to contribute to the scrap book, but the scrap book never stayed still. Akasha did a page or two and then (Lyndsey) enigma-rising contributed before I sent it on to Jay. I think in total I had the scrap book for 11 days before forwarding it to Jay. Apart from all the effort put in by ukh members, the postage alone cost me £3.75. So when its done its rounds, its going to be a huge investment in postage alone, for it not to be sent registered post. Maybe along with a time limit, a condition of forwarding with recorded delivery or alike. So that if a member happens to pass it on, then there is accountability or proof of postage.
