I just tried to send a private message via a "Contact Us" form I found at http://www.leapfrogsoftware.com/company_info/contact/ and received this in my email: Hi. This is the qmail-send program at web1.thna.net. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up.
