I'm integrating Facebook Event walls on my site using the JS API.
Some events have "open" Walls (in that any logged-in user can post to them), some have Walls that will only accept posts after a user RSVPs, and others have their Wall turned off completely.
Is there a way to determine which is the current setting so I can hide the comment box when appropriate? The documentation does not seem to suggest I can:
