Having a full_name and a usual_referent_name would seem to work. full_name - Matt S. Trout usual_referent_name - Matt (for "normal" stuff) full_name - Matt S. Trout usual_referent_name - mst (for "geek" stuff) and, yes, if I'm registering with a site for both, I have to pick one. But at least no matter what my full name is that way I can enter it.
