Validating an email address

[kromagnon]

If I have a form where a user needs to put in an email address, how can I test that to make sure that it is in fact an email address (something@somewhere) and not just crap(crapcrapcrap)

Jordan, you have a function in there ValidateEmail2 that isn't in your code above. This function wont run.
