For the time being, I have changed the wording in the main language file from:
$txt['allow_user_email'] = 'Allow users to email me';
$txt['allow_user_email'] = 'Show my email address on the forum (not recommended)';
If I change the template, when there are updates then my changes are lost.
Please consider changing that verbiage as it's very unclear. Most of our members thought it meant allow them to receive emails from other members via an interface, not expose their email publicly in the forum.
