While we're at it, here's a list of other things to add to the "How to Ask" page and reminder text:

• Don't type your question with alternating caps, like

   mY cOmPuTeR iS rUiNiNg My LiFe! HaLp!
  

• Don't use 0s for os, 1s for is, 3s for es, and 7s for ts, like

   1 h4ve l1nux 7r0ubl3 guyz, 4 r34l
  

• Avoid using more than one exclamation point or question mark at the end of sentences, like

   I spilled coffee on my keyboard!!!!!!!!!!!!!!!1 What do I do???!?!?????????
  

• Don't sign your posts with your social security number and mother's maiden name, like

   Just press F5 to refresh the page. That should solve your problem.

• Don't pepper your posts with racial slurs.

• Don't include pornographic images in any screen captures you include in your posts.

Et cetera, et cetera....

My point is that some expectations are common sense and (nearly) universal, and it's a fool's errand to start including these sorts of "pointers" on the help page.

Sure, maybe an automatic check for all caps could be useful, but my feeling is that this is a relatively rare problem that is already effectively addressed by the site's community review processes. It's probably not worth the effort to implement. Sorry.
