Have you ever been confused when someone changes their username or avatar and you don't recognize them? How about a little mini icon (like ebay has) that shows the other users that you have changed your avatar or username. The admin could show the icon for X amount of days, where after that period it would simply dissapear. It would be placed near the avatar and be small and non intrusive. The admin could also have a setting to "show past avatars/usernames" link on the users profile page. That way there is a history and everything is upfront. I think this little feature would be yet another thing to really set Xenforo above everyone else. What do you think? Anyone want to try modding this?
