Hey All, I was creating a post in the REACH group and found that prior to joining spaces I was able to add them to the To field. Then when posting, it would let me post. I noticed after that it is because I hadn't actually joined those spaces. Upon joining them, my post went through. I don't think we should be able to add spaces to the To field prior to a member joining, It's confusing, and there is no pop up or notice saying that you need to join a space prior to posting in them (hence, the spaces shouldn't show up in the To field)
