Uncle Phil is a member of a couple of online screenwriting groups. This has led to me striking up a few friendships with other writers. some of the writers have provided me with proofreading and occasional feedback. One of the group leaders also provided me with a lead that led to a recent script request. However, I'm not a member of a writer's group that meets in-person on a regular basis.
Uncle Phil would love to see you post stories about your experiences with either in-person or online screenwriting groups. Feel free to post the good, the bad and perhaps even the ugly.
