JYP Audition 2011 ; I need helpp !!?

I registered as a non-member and I accidentally didn't put my real name in where it says Username because well.. I thought you were suppose a "username" .. heh . But, I put my full real name on the 'Self-Introduction' so is that okay? I know I can't change it because I didn't register as a member. Should I maybe.. re-register? But, I don't know how to register as a member .. Please help me !
