It's often helpful to quote something from a previous post or in the documentation, but none of the built-in formatting options really work for setting off a box of text (the code macro doesn't line-wrap, so it won't work well for this).
It's possible to add a quote to a post manually by switching to the html view (using <blockquote>...</blockquote>) but it would be great if whatever jive macro handles a simple quote-style box could be added to the editor toolbar.
