following situation. I'm currently maintaining a forum, which boards were for years invisible to guest users. As activity over the years dropped down, I'm now planing to make the forum visible to guest users, so that posts can be shared on facebook and to improve the find-ability(?) over search engines like google. We are talking over several 10000 posts.
However a few people are currently complaining about their posts beeing suddenly "public" soon eventually and they afraid google will steal "their" data (even if registration is not validated by anyone). So I would like to offer them the option, to mark all their own posts as private, so that guests can't see their posts until logged in. If possible, users should be able to enter a date, from which on their would like their posts beeing "private" or "public" (e.G. please mark everything before the 1/1/2019 private).
Has somebody an idea for an extension to manage this? Or do I have develop my own? Without looking to much into the dev docs, is such a change on the security and visibility system even possible? From the point of view of the rights management acp this already looks quit complex.
Looking forward to hear from you,
