Hi Marco
Your plugin has saved my sanity, so I’ve no complaints!
On this particular issue, I’ve edited wp-login in the root directory for a simple fix: I changed the text ‘A password will be mailed to you’ to ‘We look forward to meeting you!’ (see below). That seems to work fine – no code changes as such required.
Obviously it will go on the list of ‘things to check’ when I next upgrade WordPress.
<?php do_action('register_form'); ?>
<p id="reg_passmail"><?php _e('We look forward to meeting you!') ?></p>
