For many years, I ran a mailing list where Oz fans could talk about Oz in all its aspects. Recently, however, for both personal and technical reasons, I decided to wrap things up and close the list. But this is only temporary, as I plan to start the list up again in a new environment in the not-to-distant future. So if you want to be a part of the new list when it starts up, please feel free to drop me a line, and I'll let you know when the new list debuts.
In the meantime, a great place to interact with fellow Oz fans is over at the International Wizard of Oz Club's message board—and no, you don't have to be a Club member to participate.
