What would you say is the best/most active forum or website for an mTurk beginner besides r/mTurk?

In the FAQ for r/mTurk, there's a beginner's guide mentioned that's on mTurk Crowd.com. The guide mentioned a few helpful threads for a beginner and a regular thread for "numbers" HITs (HITs that are good for building up your rating) that seemed like a good resource. I googled about mTurk forums and there's several to choose from.

What would you say is the best forum to stay up to date on mTurk and is a good resource for a beginner? In addition to r/mTurk.
