In developing my new WP theme, I installed the nifty WMD Editor Wordpress plugin by my buddy Chad Coleman, but ran into a bit of a problem.

After setting it up for my comment block forms, I later created a tiny contact form in my sidebar. When viewing post pages with the comments block, the WMD editor took over my contact form textarea and left my comments textarea untouched (WMD, by default, plugs itself into the first textarea it finds on a page). Obviously, I needed it the other way around.

Digging through the WMD readme I found a very simple solution – in any textarea you want ignored by WMD, give that textarea a class of wmd-ignore. WMD will skip that textarea and move on to the next.
