I have attached PDF brochures from Premium Chess to the first post in this thread. The brochures which describe their offering and offer a question and answer format to some common questions which you might have about their offering. In short, there is no cost to the federation. There are quite a few benefits including potential for 20% of revenues from premium members and an online forum to play games which are FIDE rated. The platform offers the ability to provide online lessons and classes. I believe that anyone with a FIDE number can register for a free basic membership. There are also provisions for a free membership for children under 12 years of age.

I have been talking to the president of Premium Chess, Carlo Stellati through email though we have had some technical and timing issues in organizing a phone conversation which I expect will occur this week.
