If I were an actor then I would go anonymously go to various on-line boards / discussion groups and plug my stuff. Self-promotion can be very helpful. If people didn't like my work, then I just would try
to not read it.
Didn't Marina Sirtis go to TNG conventions in the early days of TNG because she knew that TPTB were thinking of getting rid of Deanna Troi? She really saved her job by communicating with the fans!
