If you want people to join you have to give them an objectice and a plot. You have no chance in hell of anyone joining no one will know what factions are available, what class's, what weapons ect... oter wise you will have no one replying accept me offereing you suggestions on how to attract people. I'm not trying to be anoying I'm only trying to help. If in doubt look at other RPG's and see the opening post they will give you an idea of what to do.
I know what you're thinking, I know how you're feeling, Believe me. You're not alone.
