Updated it so you can edit the message text/html via the options panel.
uninstall then re-import should delete the unused templates.
if you wish it to only send on visit inactivity as opposed to posting inactivity find:
PHP Code:
$result = $vbulletin->db->query_read("SELECT * FROM " . TABLE_PREFIX . "user WHERE lastpost < '$datetime[lastpost]' AND emailDate < '$datetime[lastemail]' LIMIT $quantity");
and replace with:
PHP Code:
$result = $vbulletin->db->query_read("SELECT * FROM " . TABLE_PREFIX . "user WHERE lastactivity < '$datetime[lastpost]' AND emailDate < '$datetime[lastemail]' LIMIT $quantity");
in remindermail.php
I will update this so you can select via admincp also, in due course.
