Re: Last Blog Post
All of the modules are limited in size by default so they fit in the columns.
You do not mention using the MODULE plugin to display the last_blog_posts module, but I am guessing that is how you put it in your "content area".
The MODULE plugin has an "module_style" inline CSS parameter that you can use to change the width of the displayed modules.
