What does it do ?

Make use of the parser to process forgot_login_email system setting value.

Why is it needed ?

To :

1. ease the edition of the email (ie. chunks might be more convenient)
2. allow i18n
3. use additional tags (snippets/chunks/setting...)

To do before merge

• make sure unsetPlaceholders will not break anything

Re your to do, I guess unsetPlaceholders could unintentionally remove placeholders set before the handleForgotLogin method that were overwritten. One hack-ish way I've prevented something like that in another project was something along these lines:

$originalPlaceholders = $this->modx->placeholders();
$this->modx->setPlaceholders($placeholders);
$this->modx->getParser()->processElementTags(...);
$this->modx->placeholders = $originalPlaceholders;

Yes, that would do the trick i guess. Thanks
