Jelly,
I commend you on asking the question and I hope all have given you both insight and information to aid in your journey.
Because I am Active Duty Military and always on the move at a moment's notice to protect our country, I could not find a sorority to fit my schedule (nor school for that matter).
So instead, I was part of an Illustrious Group who founded the first and only Military Sorority (Sigma Phi Psi). End result: Different is good and we are able to fulfull the dreams of military females who too have been too busy to serve our country to maintain school and another sorority.
This is just something else to add to your information base for others to know.
Enjoy the journey!
