Online communities for reinforcement learning? • /r/MachineLearning

Are there any active communities (forums, Q&A) for reinforcement learning? For machinelearning in general there is this subreddit and the freenode irc channel for example. But their communities seem both to be mainly focused on deep learning. There is no freenode RL channel and the subreddit is quite dead. I am self-learning RL and often have questions (practical and theoretical ones) and am not quite sure where to ask or even where to get relevant news and an overview of the state of that field for.
