That is a good suggestion. I just kept clicking on stuff until I got something to work.
I will add that to start a blog, you just go to "My Blog" and have at it. If you don't give your blog a title, it defaults to your username.
To reply to someone else's blog just click "reply" at the bottom of the post. I think that the author can enable or diable replies or only allow a reply after its been moderated first. I'm assuming it allows the author to be the moderator, so if you want to approve the replies beforehand you can. Might be a good idea if you are blogging about something controversial like your support of the Brady handgun agenda.
Otherwise, I've just been clicking around and having some fun with it. It's a nice feature.
