Player/GM ratios have always been an issue in TableTop Games. Being an online VTT just means there's even more demands for those same 4-5 seats even if the ratio were the same. If you don't make it into a game, keep applying to others. Get to know folks on the forums and chat. Network socially, be helpful, etc. It takes time to get into the first game or two, but once you do you'll generally find that groups of players stick together and help you find other games they themselves play in. Alternatively, you can always start a game up, yourself. It's often a trite response, but its really very appropriate. The tabletop genre in general needs more GM's, and you'd have no shortage of players willing to join you, even if you're learning it yourself as you go!
