Yes, I take all of those points - I've built computer systems before, though I'm an amateur. I'm a great believer in paper in its place, and it may be that we'll go back to it, but It's a good exercise for me, and free to the club.
We seem to have all of our 100 or so members well domesticated with e-allocator these days. We had those discussions about people not being computer literate, but even our most senior members - in their late seventies - manage fine. And in the unlikely event of queues in the clubhouse, we can just add another computer - they are after all, easy to come by if you don't want new. The current one is 5 years old running OpenSuse.
So, when I finally finish, sometime in the next few weeks, we'll give it a try and see what happens. Those in the club who do the various admin jobs are looking forward to the figures arriving in a csv file, rather that Tippexed A3.
Oh, and this is just the booking sheets, not the tech logs, though if this is successful we'll certainly be looking at what we can change of the current system. But not yet.
