Auto-Capitalization of Title and Index Title fields

Please review this email which was shared today on the Mods list. Can this be incorporated into Drupal for the auto-capitalization of the Title and Index Title fields?

We decided to standardize on the AP style for capitalization of titles. But adherence to this rule is a bit tricky and our use of it somewhat inconsistent. Here is a handy website that makes it easy to capitalize properly for Portside. I would encourage its use.

See the Title Case Suggestions module - https://www.drupal.org/project/titlecasesuggestions - implemented initially for Portside.
