You might have better success contacting the folks at NukeCops.com. They are working on stabilizing the system, and making lots of changes to it. You can place a bug report through their forum (you'll need to register).
I don't know if they will doing anything about it, per say. They are slaying a lot of software internals dragons. And the difference between "username" and "nickname" is kind of like using "quid" rather than "pound sterling." ("Bucks" and "dollars" for those on this side of the pond.
)But give it a shot. They may just change it for the next software release.
