I'd love to have you on board! Alas, I think three males and three females works out rather nicely, both with the gender balance and the fact that the groups in the series - from what I can remember - tended to be balanced, too. I could
be persuaded, but it would have to be a character that made me sit up and go "WOW." Alternatively, you could always play as somebodies Digimon Partner; I know some players here actively prefer having their Partner being played by another player, so...that's always an option!
Or, if you don't mind playing a male character, I don'tmuch care whether the gender of the player matches that of the character
