Is there a ready-made cms/script with such functionality?

Question

CMS

More or less like this.
- Registration/login for users.
- Pages for content, let's say with news.
- Function "Subscribe / unsubscribe" to the news.
- A notification system that informs subscribed users that "This news is lalala" has been updated.
It's just that if something like this has already been written, I don't want to reinvent the wheel.
Thanks in advance!

Answer 1

I agree with archelon, the same WP with plugins does this once or twice.

Answer 2

Joomla + JED

Answer 3

Any CMS from the "universal" category (see Wordpress, Drupal, Joomla) will allow you to do this using the appropriate extensions.

Answer 4

Seriously, they described the most banal blog on WP
