Joomla plugin allowing user to sign for articles updates

Question

I'm looking for Joomla's plugin allowing user to sign for page updates (articles/forums etc)

Would be great if this can be integrated with joomla's user profile (kind of checkbox determining if user shall be notified content changes)
