the latest version on the forum software has it as a feature... and it's very annoying ! ![=]](https://www.theminiforum.co.uk/forums/public/style_emoticons/default/oompf.gif)
If you want to use capital letters as an abbreviation, it won't let you! 
so you can't have things like MOT, DVLA etc etc 
I believe its been in the last few versions, and I think turned off by default. At least its a feature I had to turn on manually, mainly because I was sick of having to retype titles that had been written completely in capitals!
Now I'm getting sick of having to move topics all over the place, so I might just change things so no one can start a new topic, and you'll all only be able to reply to existing topics!
