I also have attachments, that are viewable by registered users. Attachments are NOT viewable by unregistered/unverified users. I would like to keep attachments not viewable by unregistered/unverified.
However, on the portal, and only the portal, I want to explicitly give attachment viewing permissions to everyone. So that if I use the ATTACH bbcode to embed an attached image to an item, that attachment is viewable by everyone who views the portal page, even if they aren't logged in,
