I hate to do this but it's probably best all round.
1) When leaving comments, I'd be a lot more comfortable if you just left your initials rather than a name. Not really a big deal but it would put my mind at rest.
2) Try to keep comments work or school-related. If you want to exchange personal messages open a Twitter account. The bonus there is you can also keep up with my HILARIOUS tweets.
3) I won't have ANYTHING that looks like people arguing in the comments boxes. It might just be in jest but these things can easily be taken the wrong way in pixels. You don't want to upset anyone, and I don't want to have to bar anyone.
