Hi guys,
After waking up this morning, I realized that we don't have room
numbers for the recitations in the syllabus. Do we know the locations,
or does that still need to be decided?
If someone does know, email me, and I'll put it on the website.
Jeremy
I sent this to the wrong address <mbc195-tf(a)lists.fas.harvard.edu>
instead of <mcb195-tf(a)lists.fas.harvard.edu>
the first time.

Hi,
A few more corrections and comments are listed below.
Let's talk at 5pm about this. Where is Greg's lab, exactly?
