Thanks for all the feedback. I think I got the answers I was looking for. I have no plans of doing this professonally - just for me. I've only been asked for my log book at Gilboa Quarry when wanting to dive the deep end. I don't know how they would have reacted if they were not signed - but don't care. They don't require it to dive the shallow end. None of the Great Lakes boats I've gone on have ever asked for my log book nor have any of the 6 to 8 liveaboards I've gone on. I do plan to keep my xl log up to date as I want this for me but I hate taking my log books on trips with me, chasing dive buddies down for signatures, getting them wet on dive boats, risking loosing them ... Since it's for me, better to keep it in the computer and bring hard copies on trips just in case - hard copies that I can afford to loose. Again, thanks all.
