i realized that the Blog-posts are actually missing the PRINT view.
If you print a post it would also print the background-image, the menu and everything, while the actual post only takes 30% of the printout so you will have 2 pages for a short Blog-Post.
Actually i feels more like a bug.
Also, you cannot access the BLOG-Data via the Databases yet...
It would be great to create a pdf from a blog post, so you could send it to people.
