I'll be blunt and say that it just gets worse for you with each post you leave.

NEW MEMBER HANDBOOKS ARE NOT THE SAME AS MEMBERSHIP HANDBOOKS!

Membership handbooks are usually in the possession of the Membership Chair (or whatever Tri Sigma calls it), the President, and the Chapter Advisor.

Your best bet would be to contact *YOUR* Chapter President or Chapter Advisor since they know *YOU*. I wouldn't bother contacting the people at the schools you're considering because judging from what I've seen here, they probably won't even take you seriously.
