Question regarding community service?

Hello to everyone!

I have a question. I am going to be a freshman this fall. I am interested in joining a sorority (BGLO). I have heard from other messages boards and this one, that one requirement to be considered for membership is having done (and doing) community service and/or being involved in student orgs. Now, since I'm coming outta high school, I will say that I was very active there. I was a cheerleader all 4 years, ran track one year, I was in the National Honor society (I was Co-Social Chair) and I was involved in S.A.D.D (I was secretary). I also was on a special team of SADD where we went to local grade schools and talked to 5th and 6th graders about the pressures and dangers of drinking and driving and doing drugs, etc. Now, I've done all this but I haven't really done community service. We did a little in National Honor Society, but not that much.

My question is, if I apply for membership for a sorority, will any of this count or do I have to do other things in the ocmmunity? Also, why can't people join or be considered for membership if they've never done comm. svc before? What if the reason they want to join a sorority is so that they CAN do service through the sorority? Why is it necessary to bring that to the table? I can understand that if you have it, it helps, but why is required? Why can't it be highly recommended instead? Ok, sorry for the rambling and I apologize if I offended anyone, I was just wondering.
