A string variable containing the email address of the currently logged-in reader. This is empty if the reader is not logged in or if the reader has not provided an email address in their account settings.
It can also be used as a boolean variable; it is true if it contains a value.
Blogware account holders enter their email addresses in the Email text field of the Settings section for their account.
Example
The example below displays "Welcome, " followed by the reader's email address if the reader's email address is known.
