Eml synthesizers

Hello to all,
Twice now this group has been hit with porno spam posts. I thought that 
by changing the group setting to require membership approval, I could 
prevent spam but they still got by me. From now on I will be actively 
screening new pending  members before allowing them to join. I'm hoping 
that will will put a stop to it. Any other suggestions appreciated.

Thanks,
Your Group host
