Validates email doesn’t seem to work with international extensions like user@domain.com.au

@bjhess – Yeah, replacing the backslash (\) with a \ entity fixed the problem. Unfortunately I have had to do this type of ‘fix’ one to many times with WP. But once again, thanks for the heads up on the typo.

@bjhess – Thanks for catching the typo. You are right, it doesn’t work without the backward slash. But the typo is caused by WordPress itself. It seems that I do in fact have a slash in the post when I edit it, but when the post is display WP removes that slash. Maybe i’ll escape the back slash itself with an HTML entity.

Wondering if this line ever actually worked:

validates_format_of :username, :with => /^w+$/i,
  :message => "can only contain letters and numbers."

I think the ‘w’ needs escaped in order to represent any letter and number versus simply the character ‘w’. So the regex would look like: /^\w+$/i
