Hello Mikey,
I strongly echo the words of my Brother Greeks above.
You may want to take a look at
www.nicindy.org, the website of the National Interfraternity Council. There is a section for you and your parents about joining a fraternity.
Also, probably every national fraternity has a website. Delta Tau Delta's is
www.delts.org. There is a miriad of information for you and your parents. From there, you can also link to the Beta Omicron Chapter at Cornell.
Most other fraternity website address will be something like that -- some permutation of their Greek Letters or nickname. For instance,
www.sigmachi.com. (I'm not sure that's an actual URL, just using it as an example)
The single most important piece of advice I can give is to choose well. Be sure the men of the chapter are ones with which you are compatible. Remember, once you're initiated, you're a member for life.
And with that in mind, once you graduate, remember to be prepared to give something back to the fraternity as a mentor or alumni advisor. The committment you make is lifelong, and so are the benefits.
Be ready for a lot of work -- and a lot of fun. And by ready for friendships which will last forever.
Best of luck to you.
Fraternally,
DeltAlum
