phatwp – you’ll want to edit the template for Single Events, or otherwise hook into the organizer meta.
The tag for the organizer email is: tribe_get_organizer_email
If you use the plugin you’ve linked to and create a template override, use the following where you want the organizer’s email to appear, obfuscated of course:
$emailaddress = tribe_get_organizer_email;
echo eeb_email($emailaddress, 'Send a message');
or ` $emailaddress = tribe_get_organizer_email;
echo do_shortcode(‘[eeb_email email=”‘ . $emailaddress . ‘” display=”Send a message”]’)`
There are many other ways for obfuscation, including simply using a contact form in place of listing the email address.
