I too have purchased the paid version of this community newsletter and it does not work. It sends out about 492 and should have sent over 3000 news letters - it just stops.
Provb.org Support suggests to contact my host, I did, Hostgator, and they said it's not on their end. I have paid for this mod twice in fact and I still can't use it. Very unhappy customer with
Provb.org support and product The Community News letter. The big downfall is you can't even test the product or you would be sending your members annoying daily newsletters.
