I received a question the other day on how to reposition the blog info (author, date, categories, tags) from the right sidebar, to under the blog entries, and then how to remove the space left from the right sidebar (which isn't really a sidebar at all) for the Beatrice template.
The "right sidebar" for a Beatrice blog isn't even a real sidebar (in that you can't add to it via the 'Edit Content' mode). It's simply where the blog info is stored.
The only way I was able to move it was using jQuery, which I'm no expert on -- my hope is that someone with more experience can offer a simpler, or better optimized version of my code.
Anyways, see below for 'Answer' on how to do this.
