Making hosting bookings in the calendar for when one is going to use the space is one of the responsibilities of having shutter access. Too often though, members don’t make bookings, and that’s really inconvenient and difficult for members without shutter access.
A suggestion then is that members who have not hosted at least 10 hours in a year should lose shutter access. Either they don’t need it or they aren’t meeting the responsibilities that go with having SA. If everyone with SA hosted at least 10 hours a year, then access would be a great deal easier for members without SA.
Personally I’d rather members with SA just make bookings as they are meant to - that would be a better way, but that’s not happening.
If you are a member with SA who would find it very inconvenient if you lost it because you have booked less than 10 hours hosting in the past year, then rather than gripe, start making bookings for when you come here. Bear in mind that members without SA outnumber those who have it, and have an equal vote in members meetings.
