Around three years ago, Mr. Habibian told me to check out Ning (which he uses). I signed up, took a look, didn't want to continue with it, and never used it again. Then, last week, I received a few emails informing me that I owed them a whopping $2.07 for my overdue account...
I SO want to respond with "I NEVER USED Ning!!"
I am your teacher. Obey me.
