Email addresses with apostrophes in aren't accepted as valid.

[oharab]

When creating a new account and the user has an apostrophe in their name, the user validation fails and the user can't be created.

The address is valid, as per RFC 2822, I can't be the only Irishman who struggles with this, daily?

@oharab Thanks for this.

I'd like to say it was a conspiracy by the English to further oppress those from The Land of the Bogs and the Little People, but sadly I think it predates any English involvement in the project, so on this point we're blameless.

The current email validation regex is @"^(([A-Za-z0-9]+_+)|([A-Za-z0-9]+\-+)|([A-Za-z0-9]+\.+)|([A-Za-z0-9]+\++))*[A-Za-z0-9]+@((\w+\-+)|(\w+\.))*\w{1,63}\.[a-zA-Z]{2,63}$"

I think this could actually be simplified by replacing [A-Za-z0-9] with something more inclusive (far more chars are allowed, as you point out), which would get rid of the need for some of the repetition.

Do you feel like suggesting a better regex?

Based on info at http://www.regular-expressions.info/email.html how about:
^[A-Z0-9]['A-Z0-9._%+-]{0,63}@(?:[A-Z0-9-]{1,63}.){1,125}[A-Z]{2,63}$`

I've tested it online and it works with my address and some others I tried out.
Once caveat I'm sure you're aware of is that if you're passing the email address round in javascript, you'll need to sanitise your output to prevent possible SQL injection attacks.
