What we’re about
This group started as something impulsive, where people could find an event and maybe other people might like to go to it as well. Over the years, sure, it gradually evolved, but hopefully this element of excitement and impulsiveness remains, so that when people see an event listed they may think "I'd like to go to that" or "I wonder what that will be like".
So the whole idea of this group is that no one knows what to expect.
Except ... most events will be free, some will include food or drink, and no member will have to contribute towards the group's costs (although everyone will pay for their own theatre ticket, cup of coffee, whatever, that's only fair).
Except also ... this is a group to have fun, enjoy, make new friends. It's not a group where people say they're coming to an event and then don't turn up. I know emergencies happen, but if so, just say send a message, don't leave the unfortunate organiser just hanging, continually waiting for someone who won't be arriving. Please.
