Molly answered already but I will add that it's the best of the several photography forums I tried and it's a rich resource for learning and support. Watch for sales on membership. The best deal is 60% off Lifetime membership on Black Friday, which I think they've done every year. It's what I did in 2010. I did a trial of Skill Share after seeing a YouTuber advertise it and offer a deal (I think it was Today I Found Out) a year or two ago. It looked like it could be useful but I didn't manage to spend much time on it during my short trial.
