Ahoi,
Cool to See other BFG Tournaments.
May you like to Host it via
tabletopturniere.de it's an nice Website to Host Tournaments and there is an Ranking include. It's Free for Players and organizers who like to Host Tournaments with less than 16 Players.
May you give it a try we use it Since years in Germany. And yes there is an natinal and international BFG Ranking on this Site. Manly with Players from Germany and France so far.
Cheers
Whiro
