How am I able to setup standard forum behavior of automatically sending a "new reply notification" email to users who've posted in a forum thread, each time a reply is posted?

I noticed the Subscription module, though apparently this doesn't automatically setup subscriptions unless the users have activated it in their profile.

How can i make flexinode custom page type act as a e-commerce product? I want to make custom product type. Thank you in advance!
