No, this is a good idea! I don't mind chatting here. :)
I agree with them not knowing each other's real names. I am going to have to come up with a username, I have a couple of ideas, but it would make more sense then if they knew each other's real names. Did you have a username you were going to use?
Also, I have a few questions more. I've been struggling to try and come up with a reason why my character would bully your character. He wouldn't just decide to be a jerk out of the blue and I don't want to make him inherently a nasty person to everyone, so I've been trying to find another angle to go off of. So I was wondering, what is it about them chatting online that makes them like each other so much? What is something he would know about her only online that makes him like her? What would be something she would do it school differently that she doesn't talk about online?
