Hola,
I'm afraid I missed this request. I've only just realised that spam
was coming through this group. I think my own spam filters probably
killed most of it.
I've changed the settings so that any new members messages are held
for moderation. That should close the spam loop. Would anyone on the
group like to be promoted to a group admin? I'm happy to hand over the
group to anyone who is interested.
Warmly - Callum.
