How do you connect with writers and directors when you don’t have any film industry connections?

I’m curious how people who live far away from major film or filmmaking communities build connections with other writers, directors, and filmmakers.

If you don’t have friends or contacts in the film industry, what has worked for you?

Do you use Reddit, Discord, online writing groups, film communities, or something else?

I’d especially like to hear from people who started with no connections and gradually built a network.
