I think in general the thread title "shouting" correction, where shouting (i.e. ALL CAPITAL LETTERS) isn't allowed and corrected needs rethinking. My suggestion is, it should simply check for a certain number of capital letters, say 10 capital letters in a row, and then revert to the Title or Sentence Case correction. This will allow for title's like "My Problems with IE 10" and won't mess up "IE". I also think it would be cool, if thread titles could be generally corrected by the user, but that is another suggestion.
