Yeah Ive used the pro version and it was a very nice improvement over the core vB application.. I actually still have it but disabled it for reasons i dont remember anymore. But i do know i loved the product. However i will not re enable it in anticipation of converting to XF in the next few months.
I was wanting the pro version for XenForo. He seems to have fallen off the face of the earth. He is not in his own forum. I wonder if there is anything similar being developed. I wanted to use his as it would do what I wanted. I guess I will make a post in requested add ons.
