When you perform a Microsoft Article Search (from the left menu of kbAlertz.com) and you are logged in, your search is saved, and can be used again, by simply clicking the search text.
We currently save your last 5 searches, that were successful in finding results. If a search doesn't have any results, it is not saved. The idea here, is that it doesn't seem to make sense to save a search, that didn't bring back any results.
Just to reiterate, you must be logged in for this feature to work. If you can't log in, becuase you don't know your password, please use this Send My Password feature.
