I Just bought my second copy of Testify. This is NOT however because I was really satisfied with it. Yes, it does the job - no question there. Unfortunately, it stopped working on a site that we upgraded the version of DNN on.
The reason? It ran out of activations. On a site where it was already installed.
We have been unable to get a response from DNNDev (we've tried three different avenues) - and we owe it to the customer to get it working.
So I'm buying the same stupid module again. I hope they give me an activation when I re-buy this.
