I remember my excitement from a couple of years ago when I first set up my class blog. I looked at others' sites, thought about what would interest and work with my pupils and then gradually developed it, page by page, mistake by mistake.
For those starting out, I've just added a document in the Documents section with some sample text for various different pages of a class blog. They are fairly standard, but might help some, setting out on the blogging journey.
Hope they help!
