Hello,
I've encountered an issue. If any of the tags have the setting that allows "Browsing the forum (discussions and users)" by unregistered users (for example, a tag for general announcements), then setting "Show to everyone who has access to these tags" on any forum post will also display that post to unregistered users.
Here's an example, the unregistered view:
I have also noticed that when I click on "delete forever" inside such a help tag any tag, nothing happens...
It works fine when I disable the extension...
