I guess that can be useful.

Perhaps would it be useful to add it to the email template "new reply notification"?

Thanks for your answer, ... but the point is that I don't know how to insert a link with post ID in the notification email.

It seems not to be possible with the plugin parameters, the only proposal is the shortcode , which lands at the top of the thread.

Please see in attachment, the way my email template is set.

What should I do to have a direct link to the answer post?

If the link is not for a current post(with post ID), it will jump to the latest unread post if you have enabled Topic Links - Jump to First Unread Post from Dashboard > wpForo > Settings > Action Logging & Views

Since the "great update" (v2), the links in the notification emails don't jump anymore to the last post of a thread. 

Instead, you land at the top of the thread.

Is there something changed about this (very practical) function?

Did I miss a new parameter somewhere?

Thanks for your help!
