I have joined the club a while ago and wanted to express my opinion about the products and customer support. While the products are all great and simple to use, I was more impressed with the support I got from them. Every query I sent was replied timely and a very friendly manner. It's beeen a long time since I found this kind of one to one support online. to me, it's worth paying for the support alone!
Among the extensions, the "Add a friend" module stands out for me. I got a ton of friend request via that module from my readers. If you are not using it already, i highly recommend it.
