I wonder if that's just HTML - normally multiple spaces get condensed to one. I'm not sure how to fix that easily. You could find everywhere a user name is being displayed and change spaces to  , but that seems like a lot of places.

There's a function called fetch_musername() in includes/functions that gets the "marked up" user name, so if you changed that it would probably handle most places, but I know there are some places where it's just the bare user name.

In retrospect, the single-space thing is probably a good thing because having people with the same user name other than spacing could get confusing (but I'm sure you have your reasons for wanting to allow it).
