Two questions:
What is a letter of intent and is it a prerequisite to attending rush?

How do I research the chapter I want to join, if the chapter is a city chapter (not based on my school campus). I have no idea how to find out who the president of the chapter is or a contact #. i have researched the sorority on a national level extensively, but i am completely stumped on how to research the actual history of the chapter. the chapter does not have a website.
