as on topic, I need some plugin to offer my users ability to subscribe/favorite CATEGORY of each question and question from questions-list and from question page (where favoriting for question is available but for category - no).
Also would be cool to add ability to subcribe user from users-list and question-page (author of each question) and something like this with tags too.
Anybody has some idea how to do this or plugin or want to make this?
I can pay for this immediately. Hope it's not very hard to do I'm think but I don't know how to make this on my own :/
