Take two. Apparently you have to click on the post title to get to the comment portion. Not sure I like that. I miss the little button that says "comment here". I shall look into fixing. In the mean time, click on the post title and try a little commenting action.
(Wondering what to comment about? You can tell me if you prefer the comment box to be on the same page as a post or if you like it when it opens up in its own little window. It's the age old question).
