You may be right my friend. But the way the posts there can be sent is a kind of the spam protection. There could be a lot of spam if the folder would be accessed by all. In the way the content there can be controlled without getting unwanted posts with violating the forum rules about advertisement , trading etc... Of course we can edit the "Events" title of the "public folder" and add the proper info making the purpose of the forum more clear for all users.
