In looking at the fraternity sites, it seems that the other fraternities have a decent number of members.
And who the hell wants a chapter full of joiners? I want a chapter full of leaders!!
Maybe men don't join your fraternity because they hear, see and feel the frustration that you have towards greek life or the fraternity and think, "hell, if he's this miserable, why would I want to join!?!?"
To fix the Greek System, well, that takes the desire of all of the fraternities, not just yours. Join IFC first and foremost, and get as many executive positions as you can. Change can only happen if you make it happen!
