There used to be a publication called "Dungeon" that would have a handful of fully-developed adventures in each issue. I used to subscribe to it, but my subscription was up just about the same time as my job transferred me halfway across the country, and I never picked it back up.
When I was following it, they were 1e and 2e adventures, but I presume they went on to do 3e as well.
Can anyone confirm that for her?
