another report for plugin author.
When you enter some quotes into the messages text like:
it's so nice!
...and then you send the email without entering subject, it returns with a message, that you need to fill in all the fields. And the textarea with message text has a backslash in front of the quote, like this:
it\'s so nice!
I had to add stripslashes where the print of the $_POST['email_content'] in textarea tag is.
Please include this fix in new version, or find a better one.
