Has anyone created a WIKI type area on a Muse page where users can add comments? I would like to create a space where users can add upcoming events and activities that will be visible to others without my having to manually add them in the app.
Muse can't do this. You will need to seek out 3rd party solutions that use server-side technologies. But be careful what you wish for. This will become a magnet for spam and other nonesense posts if you don't keep a very tight watch over it.
