Is it possible to have the header bar of the website (with the big logo and, most importantly, links to blog, board, etc) stay frozen as you scroll down blog or board entries? It would be more convenient to not have to scroll all the way back up the page to switch to a different section.

In a similar vein, it would be helpful to add to that header section a link that would jump down to the bottom of the page where you create a new post.
