Subscription/email notification management is a feature that is not present on profile management screens (or rather it's three levels deep in them - that is click-click-click). A user who hasn't memorized the path must look hard to find it.
I think it is a major functional area and deserves a more prominent spot on the preferences screens.
- Why not having indicators and edit links straight on preferences|Favorite Tags, showing subscribed or not (color-code the tag maybe) + frequency + "edit" link/icon. something like this:
Without it the management of this feature is hidden and hard to find.
- Also - not 100% sure, but I thought I saw an alternative (to the "filters") subscription mechanism - one through favorite tags. Am I right, and if yes could someone explain if they're really different and how to get to the "favorites" subscriptions?
ADDITION The "parallel" subscription management is on StackExchange. There, I definitely see different settings than the "favorite tags" on SO - same tags, same site - just two different subscriptions. That's confusing, to say the least.
Suggestion: Since "subscriptions" on StackExchange and "favorite tags" on StackOverflow overlap, I think they need to be consolidated. At least to the point individual subscriptions intersect (in case there are other reasons to keep them segregated). END ADDITION
