I learned to put a semi-colon after the screen name of the person I am sending a message to.
Sometimes the auto-fill would add more to the name than I intended and the message ended up not where I intended.
Example:
I want to send a message to someone named: bearis
The auto-correct might just keep on and add a few more letters, so the message would be sent to: bearisgray instead of bearis.
So now I would type in: bearis;
even when that is the only person I am sending a message to.
Just check to make sure that it doesn't change the name on you when you aren't looking.
