There are of course plenty of other things we can do with notify - the example on the last page is of course very basic.
Values of submitted pulldown menus are passed through to the query string
in the same way - just give your <select> box a name (e.g.
<select name="pulldown">) and that value is available for
putting in email forms. This means you could use the plugin for all sorts of
web forms, including basic site surveys.
It's also possible to do some basic error checking - ensuring the user has put in a message, and displaying an error message if they haven't, rather than firing off a blank email address.
Of course there is even more - just remember to use your own email address, and don't misuse it!
