 * Hi all,
 * Is it possible to add a field with unique numeric value in the registration form?
   I want users to fill their National ID so it’s important that 2 users can’t have
   the same number in that field! 
   Now I can create 2 accounts with the same National
   ID…Please help me on this one. Many thanks! Best regardsSindri
