I'm not really into AD&D, so I normally don't promote Dragonsfoot modules or supplements on my blog. However, I feel obligated to let everyone know about this module: Pop Goes the Meazel, by Todd Hughes. It's a short, small adventure, intended for 1st level characters, and could probably serve as an introductory module. It should be a cinch converting it to other versions or retro-clones of D&D.
I'm linking to it because, although I'm not a contributor to it, I did do the layout for the module. This is the project I alluded to weeks ago. Also, while working on this module, I skimmed through a couple other modules to get a handle on DF module style, and they seem pretty well put together. Anyone who somehow wasn't aware of the existence of Dragonsfoot should check it out.
