I came to know that, one of the FB fan page allows edit option to everyone in the Facebook, like a wiki. So I'm just wondering how it is possible? Can you please clarify me? Is it happens due to the public access in the settings?
quite surprising to me as well because I think that you can create notes but notes doesn't have option for user to edit it but in groups I think user can create their own thread like forums but having a wiki is new to me as well.
