Within the group having channels or subcategories so things can be organize and also within those subcategories when the trainer posts a question or something that needs a response being able to click on that message and answer within that specific message so that the feed isnt just everyones answer and the clients isnt just trying to find the original question posted by the trainer. This is how slack is built and works well and what I use but I hate having client use 5 million different apps
