Hello
Apologies if you saw my previous post, I was confused and worn out.
It might sound a bit specialised yes, I've done some thinking and I described it to be quite complicated, where really it only involves a new database of members, their member ids and renewal date, then an admin function that goes through the whole member database and if they have a valid member number and renewal date, which happens to be current then they stay in their group, if not they are demoted to non member
I think I will try this myself, thanks for your help.
