This is all CST.
I'll give you my standard, when everything is going usually and uneventfully, schedule.
Mondays and Wednesdays I have class at 11:00 P.M., 2:00 P.M., and 3:00 P.M. I usually don't get online much during or in between those times. I'm usually hope around 5:00 P.M. on those days, and should be on for the rest of the day, though I do occasionally go off with friends, but I'll be here at night for sure.
Tuesdays and Thursdays: I have classes at 10:50 and 12:15, I get home around 2:30-3:00 P.M. and am here frequently for the rest of the day and into the night.
On Fridays, I don't have class until 2:00, then another at 3:00. So I'm here from about 8:30 A.M.-1:30 P.M., and then after my last class, I'll be home at around 5:00 P.M. just like Mondays and Wednesdays.
On the weekends, you can never know. But chances are I will be on frequently the whole weekend.
That's usually going to be the norm of my availability.
There you are!
