I think the only font that can be used for monospace is "Courier New" on the jQuery forum? I think Mac and PC are both supporting Consolas font and quite many people I know use it instead of Courier, which is more used in the 90s, and Consolas does look great too. So it can make sense if Consolas is added to the forum as it is a forum that talks about coding and the monospace font should be important on this forum.
