It looks like everybody is available on Sat -Sun, so I'd like to make an appointment on Sunday 12, May, from 19.00-20.00 for group A, 20.00-21.00 for group B and 21.00-22.00 for group C. I really feel sorry that I can't do Saturday because I'm busy with ENG 500 offline program all day. So, if you are interested in our group discussion, please let me know. Our first chatting will be Sunday12, May. Please join our discussion at the stated time. Waiting so see your all.
