What's 'properly' to you, then?  Because I've been trying in my every post, and I know some others have been as well.

I don't think he's talking about you specifically but those people that don't set out there locations in there headers a number of them also aren't exactly clear about which class they are going to. They'll say something along the lines of:

"Jimmy pushed open the class door and sat down near the front of the room so he'd have a good view of the teacher."

Just from this we have no real idea what class Jimmy is in and I'd imagine it gets pretty tiring crosschecking each post you read with the conference dock. I just usually keep in mind which characters are in my classes and which aren't. Then I'll usually skip over other class posts.
