Any alternate wording? (I'm not wild about "sensitive content.")

Maybe instead of "Warnings or sensitive content" something like "Contains:" could be used? It gets the message across without the negative connotations that sometimes comes with the word "Warning". I'm not married to it or anything, it's just an idea.

Also, you've probably already thought of this, but it would be nice to be able to cut and paste a 'blank' header from the community profile page.
