Any time I try to post anything, I have to select a "place" which is all greyed out so I am limited to to where my posts go. I must be missing something here.
Within the Topliners, there are only certain subspaces where it looks like community members are permitted to ask questions. From a quick glance, it looks like the Do It subspace allows users to create discussions / ask questions. Perhaps you can try posting within there.
