President/Relevant Info... Help

[TPASteph]

Hey all,
I am seriously considering running for president of our sorority interest group next elections. (If they're held end of Fall and we're established in the Spring *knock on wood* that means I'll be the first president of our restablished sorority.) So in other words, I don't want to screw up. I've stayed up countless nights (basically every one this summer and last spring) trying to find stuff online to help me or researching stuff about the sorority we're trying to restablish or working on our website. (You get the point.) Anyway, I know a lot about our group as an individual, but I don't know all that much about the greek system as a whole. I'd really like to learn more about the workings/processes/goings-on of greek life, but I can't find much online. I'm not sure what to look up. Does anyone know of any sites that I could go to? I've been to the Robert's Rules of Order site, but the book is like $20 and that's not in my budget right now since I just got a car. Is there anywhere to download it or perhaps *god forbid* get it for free? Any help you could give me would be greatly appreciated! Thanks so much!
XOXO,
Steph
