MyBB Community Forums

hello

i wish someone help me with a mod or tell me if this option is available in mybb . I want user to register with a username and choose their forum names

Examples

Username : Test

Appear in Forums : Mickey 22

So a display name which everyone else sees? This isn't possible with the default functionality.
I believe some people submitted it as an ideo a while ago: http://ideas.mybb.com/idea/display-name

Not sure if it's been made into a plugin.
