To read or not to read? That is the question.

I could be reading some of the discussions for my class. I'm not really sure about how to use the website, and it's kinda worrisome. I'm supposed to participate in four discussions a week, and I'm not familiar with the program they're using at all. There's threaded discussions, and I have used ones similar to these, a long time ago on a BBS or bulletin board system, but not just like these. I will figure it out, settle down, and get my groove back....
