Nope I swear it's a feature that needs to be added? If it's not then I apologize, just never seen it before on my many MyBB forums made. But I don't tend to go through settings oftenly. Very possible the theme could of removed it though.
Nah just checked.
It's with the original MyBB no plugin needed.
I'll add the correct code tomorrow as I'm on my iPod at the moment and it isn't very good for doing any editing.
Closed. Feature will be re-added.
By the way.
It's a postbit button not a edited setting. I believe.
