A reader emailed me to say that, in IE, the comment "submit" button doesn't appear. So he can't comment.
I'm using Cutline 2.0.
While I'm at it, other dreams about the comments section:
1. Adding a second comment box below the threads, so people can choose top or bottom to comment;
2. Larger default comment font size;
3. Larger default comment box size.
Love the theme. It's clearly taking the world by storm - you must be proud!
