I'm completely new to the thought of screenwriting. I have so many ideas (and figure that since I'm having a hard time finding things I'd like to work on (acting) - I would try my hand at creating/writing) but am worried that if I share it too widely before its far enough along in the process, someone might take it and try to make it their own. Is that ever a worry you have? Are there ways to protect yourself and ideas? Am I just being silly?
