David Sparks has released a new MacSpark Field Guide: [Markdown](http://click.linksynergy.com/fs-bin/stat?id=r*bqlTuiXSo&offerid=146261&type=3&subid=0&tmpid=1826&RD_PARM1=https%253A%252F%252Fitunes.apple.com%252Fus%252Fbook%252Fmarkdown%252Fid622433972%253Fmt%253D11%2526uo%253D4%2526partnerId%253D30)[^f2953].
