Hello Biology students!
I will be "on call" tonight to answer your Biology-related questions, beginning at about 6:00 p.m. I will be taking a break for a meeting at 7 p.m. sharp and returning at about 8 p.m. to resume taking questions until about 11 p.m. or so.
If you do not have a Gmail account to use, I strongly suggest you make one. See you in Gchat!
