   Notes:
   
   'exclude' checks 5 conditions:
   
   a) characters that should not be in the address
   b) characters that should not be at the start
   c) & d) characters that shouldn't be together
   e) there's not more than one '@'
   
   'check' checks there's at least one '@', later followed by at least one '.'
   'checkend' checks the address ends with a period followed by 2 or 3 alpha characters.
   N.B. Javascript 1.2 only works with version 4 browsers and higher. */
