Hey again,
I just remembered that Joe had asked me to explain how to post a comment. Since I am not sure what problems in particular some of you are having, it's hard to know what to advise. But I think the main point is that you have to click on an ID--even if it's anonymous. Then in the body of the text you can ID yourself. Oh, and this might sound really obvious, but maybe it's not, so I'll just say that in order to get to the comments window, you have to click on the word "Comments". Sorry if this doesn't remedy the issue. Just keep trying!
