This is a theme that I modified
So I can't easily change the width. I don't really understand how to create themes in PostNuke, so we are stuck with what I can figure out. We so rarely have posts that are more than 2 lines anyway, this past week excluded, and if we do, they are exceptions to the rule. Anyway, if it is too annoying for you, override it with another theme, or I can go back to default.
