Just enroll in the Basic Darkroom workshop at NESOP. That will give you access to the darkroom M-F 5:00 - 11:30 and all day S,Su. Nice folks there, too. Nick Johnson usually teaches it, and he'll talk about advanced topics, too, with anyone who is interested. Very little lecture, almost all hands-on. And you can skip any lectures and go straight to the darkroom if you wish.
