The emails are good but with the recent onslaught of hack attempts it would be handy to add a line to the top of the email that says:
218 total failed login attempts.
I added it to mine with this code, but it would be nice to be in the official plugin:
$total_count = get_option('limit_login_lockouts_total', 0);
$message = sprintf(__("%d total failed login attempts."
, 'limit-login-attempts') . "\r\n\r\n"
Thanks! This plugin is a lifesaver!
