good luck with this project.
i don't get why people complain. It is up to the organizers to make their own rule. And arguably, female gamers are different from male gamers just as female chess is separate. Female gamers are also at a disadvantage socially because of all the stereotypes so they deserve their own league.
Anyway as pointed out earlier, if you complain about this, why don't u complain about Viking Cup because it discriminates against people out of the Nordic Area. Same as TSL because they did not allow Korean progamers?
