Other discussion forum to get feedbacks?

Hello everyone, I’m new here and I was wondering what other (beside here, you guys rock!) forums are great to get feedback on your work? I learn everything exclusively online and sometimes I would need an answer faster. What are the forums I could subscribe to to get fast replies?

Thanks everyone!
