Forums mIRC Help Change name in mIRC?

I was alarmed that someone knew my first name while chatting in mIRC, then I learned of the WhoIS function and found that my first name was displayed on there.
I was wondering is there a way to change that name (not nickname)?

You can never be too careful these days.

1. Make sure you are not connected to any IRC servers.
2. Go to Tools > Options
3. Navigate to the Connect menu (if not already there)
4. Change your "Full Name"

Alternatively you could use the /fullname command.
