One group Per Member
I am trying to make my site so that you can only join one group at a time! I trawled the forums and haven’t been able to find a solution – they all seem outdated.
Has anyone found a solution? Ideally when you are in one group, and try to join another, there should be a message like “Sorry, you’re already in one group, you will need to leave that group before you can join a new one”
