I was one of the original users of Reunion way back in the beginning, 3.0. They sold the PC version to Sierra and after a while it disappeared. I have tried every software product out there, and Reunion is still my favorite.
Try this link, and tell me this is not Reunion in disguise. There are simply too many similarities for it not to be. I have been using this "new" version for about three years now and you cannot beat the price!
