Not sure if this is already suggested before.
suggestion is pretty simple — be able to subscribe to any section/area
throughout the site.
For instance, I'd like to able to subscribe to the Bugs section so that I'll be notified whenever there's a new bug report made by anyone.
Similarly, being able to subscribe to and getting notified whenever there's a new content posted in the GameBanana > Blogs > General category and so on.
Basically, a subscribe feature available on almost every (possible) section/area of the site (Wikis, Ideas, Counter-Strike 1.6 Maps section, categories, sub-categories, etc.).
Would be really helpful considering if you would like to get updated/notified about any new content being made in a specific section or category, etc.
