How to create new badges?

edit

Really Thanks. But to create some new actions related to a new badge how can i do it? For example if i need to have a badge dedicate to who change their nick name too many times?

Badges are generally used to reward desirable behavior. If you are creating a badge to reward a user for doing anything "too many times", you're probably not going to like the result.

Yes i understand.. may be it was a wrong example but i can also need to evidence when there si someone that do too many times something of not correct also if can be strange how idea. For a good example i can need to have for who have a tot of followers.. ( can be a good example? ) But except the good or not good example it could be interesting if there is a way to implement our badges. Thank You

Someone has any information about my request? I only need to create others badges except that there are by default.

Are you proposing a specific badge? I could not understand what is the behavior you are trying to capture. To add badges you'd have to write code.
