Somewhat broken, undisclosed advertising

Doesn’t seem to send message text that I entered for email. What is does send is a spam request to follow the plug-in author on twitter; and he has a weird name; so the people who receive email invitations I send through this plug-in contact me to see if the invitation is real, as it looks like spam, or that I’ve been hacked. The plug-in doesn’t seem to be being maintained, and doesn’t really seem to have critical mass to drive maintenance. For now I hacked one line in the code to stop it from sending the twitter spam, but I’m probably going to dump this plugin, as it doesn’t seem to be in a condition that provides reasonable assurance that it will continue to work and be stable.
