Hi James,
This is a really great introduction — thanks very much for putting it together. I've just started using Wikidot today and I have what looks like a very acceptable blog up and running already.
One question re step 5. You say "Finally, you may want to add a "Create new blog entry" button somewhere on your site". For us newbies, it would be really helpful if you gave an example of where would be a good place to put that button. It seems to me that the nav:side page would be a good default place.
Finally, is it possible to use the NewPage module to create a page with a blank title? It'd be nice to just press the New Blog Entry button and be able to do all the editing on the new post page.
Thanks again for the guide.
