If anyone here is on Pinterest (or want to join) I've started a group board where people can give tips on docs and indie films they like. I haven't found any other group board for docs and hopes it will grow big because it's great spreading docs and indies more. It's also possible to add a Indiegogo or Kickstarter project one believe in.
