Confluence needs a note macro

Often I would like to include a sentence or two of slightly off-topic information halfway through a page (a 'note'). I'd like it to render as an indented block with an icon of some sort (like Forrest renders notes - see http://www.atlassian.com/software/jira/docs/latest/standalone-dbconfig.html, - only less obtrusive). The indentation is necessary to indicate that the note is not part of the main text. I couldn't find any other magic tags to indent a paragraph, but if there are, that would keep me happy too.
