OK, I hate it when people do this but tl;dr ... at least not the last few pages. But if what was included up to page 14 is any indication it seems people are starting to repeat themselves. I have a couple of thoughts, which also are somewhat repeats of what's been said.
First, the 1 hour rule should probably be expanded, but at the very least there need to be exceptions. Exception 1: An emergency in which the sitter has been informed that turns need to be taken should be treated the same as any pre-arranged absence. Exception 2: Once a player comes within the 1 hour rule and after efforts have been made to contact that player, sitting should be permitted at the minimum levels necessary to ensure no missed turns. If only one player has their password and that player is going to bed, this means they could clear 8 hours or so. Exception 3: After a player has missed a turn, he is considered in a state of emergency and the other exceptions apply. Exception 4: Other exceptions handled on a case-by-case basis, e.g., Goranz' posts about being in a different timezone.
Just thought of this: change "vacation" or whatever it says now to "prearranged absence, e.g., vacation"
I'm not sure how I feel about the fact that I can't play some other turns while I'm away. Sometimes, as a favor to my sitter, I try to clear the easy turns or the turns in games that are already decided to decrease the sitter's gameload. I understand how this could be abused, so I get why the rule is as it is, but I'm not terribly happy about not being able to help my sitter out while he's helping me.
Last thought is that people seem to be forgetting that these rules apply to clan wars only. It's not going to get you a C&A post (I would hope) if you break these rules. It's not going to affect how you sit for clanmates (or others) in non-clan games.
Oh and I would also like to point out that the whole "all top clans do such-and-such" doesn't seem to be true. The takeaway that I got from reading posts from people in "top clans" is that most of them do things differently, but generally try to be honest and fair. It will be nice to standardize these things, though, so everyone is on the same page.
