How to send email automatically?
The script of sending email is: Once a member comments on a topic, members who joined that topic will recieve an email.
Thanks.

That's already a feature in User Settings -> Notifications

Can you detail more?
Thanks.

If you visit the part of the user setting I referred to (ie: yoursite.com/forum/settings/notifications), you'll see the following area.
