Forums mIRC Help Question about real name showing up

I failed to realize this when I signed up...very new. I noticed it will not let me change it. I'd prefer to stay at least partially anonymous. What can I do to change this? That is, when people see my name during "info" and what have you...I even clicked on "anonymous" and it doesn't work...I can still see my name when I click on "info"...what gives?
