I didn't receive that e-mail from Linda, nor an e-mail about the 2nd look weekend. However, I did receive an invitation in the mail today, and yes, it is May 3-5. I wouldn't worry, I'm sure yours is lurking in the USPS void, soon to make its appearance. If you have any specific ?'s about the weekend, PM me, and I'll be happy to share what's in the letter.
On another note, does anybody have details about pursuing a cnocurrent MPH, while at Pitt?
