The FG virtual Con was great fun last year. It was one of my first encounters with the software.
You are more than welcome. Dakadin has done a huge amount of work and it runs a game very smoothly (combat time cut in half, if not more, with the search for tables automated)
But as I said, purchase is not necessary as I have an Ultimate licence, so anyone who downloads the unregistered version (available at the Fantasy Grounds website) can join in the weekend, which has a lot on offer and is 100% free.
