omaira17, I think perhaps the difference is the level of theater. Meaning no offense, and while there is always the occasional someone who abuses the system, in professional theater the cast gets a contact list - for many reasons! And, similar to Matt, when I collect the emergency contact forms, I always make sure they've checked which info they approve showing up on the Final Contact, which everyone gets. That is the master form of everyone who dealt w the show, including all contact info.
Having worked w many actors at all levels who have been stalked or have rabid fans (or as just a little too over themselves), I am very careful about who gets info, but it certainly helps locally with things like carpools and car trouble, and it allows those who wish to get together on their own time to review, rehearse or just go to dinner. And out of town, it allows them to connect to their companion to the museum or movie or wherever, too.
But no, never ever posted -
