Remember, it’s always good advice to change your filters often… or something like that. Now you can mix it up by checking out all kinds of actions, including what questions have recently been featured, protected or autoflagged, what links have been recently added, or what questions an individual has featured, protected, reverted, and more.
These are also on the Recent Category Activity pages, and on User Contribution and Question History pages.
This is the type of thing you just have to play around with yourself, so check it out!
And a word of advice from product mistress Pickleshy: Don’t forget to press the GO button to submit the filter.
