I think the name-accepting system is too strict and I'm proposing a change: Allow spaces and -'s. In quite some countries there are double first names (like Jan-Peter Balkenende or Lars Iver Strand for instance) or a prefix in last names (like Marco van Basten or Christophe Le Mével, or my own name) or double last names (Alejandro Valverde Belmonte). You get the point. Is that possisble? Would be fun to be able to create myself
EDIT: a ' could be nice too. Dutch have names with a 't in it, like Maarten 't Hart and John van 't Schip.
