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.
