It has an unusual name but Reelgrok is a site dedicated to filmmaking, and its attention came to my via the Indie Film list I'm on. Reelgrok has a community, blogs, portfolios and jobs. Grok name means to understand comprehensively so Reelgrok I guess then is to understand film. I spent a bit of time browsing through people's Video Reels. So if you are looking for a community of filmmakers then go and have a look at Reelgrok, I don't really know anymore about it then that, so I'll leave it up to you to investigate dear reader.
