EMail Auto-checks

Sometimes participants make mistakes typing in their email address (in spite of having them double enter them). We added some logic to check for common mistakes with common email addresses:

• Look for @gmail typos like gmial, mgail, gmal, etc.
• Look for @Yahoo typos
• We also try to correct aol, msn, hotmail, comcast, verizon, and sbcglobal if the domain name portion is the same length and all the characters are the same, but in a different order.
