Either leave it empty, or move it to a more prominent place.
As this does not seem to be a very important feature, I don't think a more prominent place would be appropriate, though.
Maybe it could be left empty, but with a toggle (e.g. checkbox) "Always add my name here". Then, gnomebaker would remember the inserted value (could be a pseudonym or something similar) instead of getting the name from the OS.
