I have too many people with typos in their email address in a field on a form. These are not licensed users so I can't have their email addresses in a lookup.
The majority of the email addresses will end with @flagstaff.ab.ca and the majority of the errors are in the spelling of flagstaff.
Can JavaScript be used to validate that portion of the address and if it is not spelled right, cause a popup window to warn them about it?
