Hi,
This seems like something that could be really useful to me but I cant get my page to call it? Am I missing some command somewhere that is needed to call custom plugins?
Wordpress Beginner :)
Thanks

Hi
Thanks for this helpful plugin but it is changing the from email for the user as well not just the administrator email .. how can I keep the " From Email Address " set in the form settings in the email sent to the user ?
