I'll check with @BILL S but maybe we accept and if they don't join a league for a few months we remove. I do think some, like Mingorance, will join us as he seems to take part in most leagues. Not sure about the others though.In my experience, they'll never turn up in the races if they don't post here, all they will do is clutter the group membership!
This is why Bill and I agreed to only join people who first posted here.
Not my group any more, so just my 2p worth...
