spring rush as a transfer?

[jcrewlover]

I am going to be transferring to a large school, with a big greek life next semester of my freshman year. I know that they already held their informal recruitment, so I have missed out on that. My question is how can I find out which chapters will be participating in spring rush this year? I know of a few I may be interested in, would it be okay to email the vp with a letter of interest? Telling them why and how I am interested in their chapter? Or is this something unheard of that would get me shot down immediately? I know I could also wait until my soph. year to go through formal, but I am worried about being a sophomore then. I just want to go about this the best possible way, and hopefully become a member of a sorority.
