A couple of people in the world haven't ever read a blog. Shocking, I know. Anyhow, one big stumbling block seems to be knowing how to comment. It is very simple. There is a line after each post that has some information such as the time it was posted, the category it is in, and then it says Comments, and if you click on it, it opens up a form, where you write in your name (or a nom-de-comment), your email address and then list your own blog if you have one. Write a bon mot, and click submit. Voila.
Uh, I think I used some bastardized French phrases; please forgive me if they are inappropriate or spelled so oddly, you have no idea what I was saying.
