Rated 2 out of 5 stars

Unfortunately, the plugin developer is making a big fuss about the issue:
"I want to place my signature above the quote when replying to an email. Can this be done using SignatureSwitch?"

For a quarter of a century, we have always placed personal signatures below our own text and never at the end of emails at EVERY company with hundreds of employees.

Guess what: It has ALWAYS been perfectly useful: Readers of the email have always seen, appreciated, and used the signature of the current author. It has NEVER been a problem.
