I had a look at the Powerhouse Museum blog. All the entries seem to be written by Seb Chan. He's listed at the manager of the blog so it may be that he oversees all the blogs and therefore his name appears - or are all the blog entries by the same person ie merely information as opposed to a forum for community input, or journal-like entries inviting comments.

I find it rather frustrating because I saved my first entry, but didn't publish it, and then couldn't find it again (I finally did by clicking every link on the page.)
I also don't know how to move things around the page within the selected template. I'll investigate.

This is my first blog posting. The big wide blogworld is out there!
