My members are driving me crazy with topic and blog titles/entries in ALL CAPS. I suggest a switch for all IPS apps to stop the shouting. Ideally, this would include a list of allowed words (SQL, USA, etc.) that would be left alone. The rest would be converted to title case.
I realize there is an add-on for this, but it only handles topic titles, not blogs or other apps. Also, defining this as custom CSS doesn't solve the issue of the caps remaining in the feeds. I'd really love this as a core feature.
