Awhile back a friend of mine told me how I could sign up for the Northeast Ohio Performing Arts Listserv [NEohioPAL]. A gentleman named Fred Sternfeld maintains it, and members of the listserv send in events in which they are involved, auditions, casting calls, free or discount shows, you name it. It is heavily theatre-centric but also has crew calls for films and poetry and other grooviness. It has over 37 hundred members and best of all, it is free and delivered daily to your inbox. If you want to know more, read the FAQ.
