When I first joined it was explained to me that shutter access is a privelidge (not a right) that came with responsibilities. One of those responsibilities was that you had to host the space for other people when you opened up.
I can’t help but feel that if people don’t accept the responsibilities, they lose the privelidge. If you repeatedly open the space without hosting then you lose shutter access. If someone repeatedly left the space unlocked all night, I’m guessing they would lose shutter access.
I suspect this will be an unpopular view with some people but these won’t be the people who are paying for a membership they can’t use.
I know that sometimes you don’t know how long you will be at the space, in this case, don’t host, wait till someone else hosts so you don’t have to make a commitment. I too have hosted and then I couldn’t do what I had planned. I still stayed for the four hours I had committed to because that’s what a commitment means.
To the point that it’s fiddly; I think this is a weak argument. It’s no more fiddly than much of the equipment we have.
Alternatively, give everyone shutter access. At the moment, everyone pays the same (barring concessions) but not everyone has equal access. I don’t think that is very fair.
The green tick isn’t very helpful if you don’t live close to the space. By the time you arrive, the space may be closed.
