Sorry JuniperEccles but due to how the titles of questions are structured, if we implemented a requirement for certain words to be all capitalised, it would send our system into loops. The title would be trying to make it Bbc, but the requirement would be trying to make it say BBC. This would cause our system to fall over, but it is something we can look into for the future.
One way to get around it would be to type BBC as B B C in the title field.
