If you have spent time and effort on MakerForums doing various different things enough to be granted “trust level 2,” you now also have the ability to create Saved Searches in your user Preferences. Under the Saved Searches heading, you can list up to five searches (just like using the search feature in the top bar) and you’ll get daily notifications of new posts matching your search terms.
This may be useful for category moderators to recognize when new members (or even experienced community members) accidentally post to the wrong category, or no category at all.
Or, just use it to keep up with things that interest you that cross categories!
