I have customized my minibb by removing the sign in box at the bottom of the New Topic post area.
The user, instead, signs in at the top, and then can make a new post.
I also have this open to the general public, with the captcha feature, so they can post. The username for a while now has been Anonymous for thos posters, using userid #0, but i have once in a while people putting in a different name when they post. Userid still shows 0.
My question is this: If the signin box at the bottom is not there when they post, how are they able to change the name from Anonymous?
