So as far as the displayed cost on a particular module where it says "$50 for a year", is waved with my Pro Dolphin converted License?

That is correct. If you decided to transfer your pro Dolphin License to UNA Pro, then the apps I mentioned come with that plan. There is no yearly fees. If you decided to purchase an app that is NOT part of the Sys, Core, or Pro apps, then that is a different story. 

And yes, I completely understand as far as investments. However, that is the risk with any investment correct? I would suggest rethinking your options and determine whether you want to move forward with UNA or not. Once I saw the new focus was now UNA and Dolphin was going away but I still wanted a "website", It didn't take long for me to decided. And yes, very tough to accept my losses. Thankfully, UNA has proven to be everything I really "needed" for a website.
