This category contains articles that have at least one listing entry where the email has no @, multiple @'s in the same email, has a double dot after the @ or does not contain any dots after the @.

To make it easier to find invalid email addresses in an article, enable the "ErrorHighlighter" gadget from your user preferences. After enabling the gadget, invalid email addresses will display followed by a very noticeable "FORMAT" warning.
