What he's referring to is the jumping between read_msg.asp and read_msg_ig.asp and the different ways each handles the Previous and Next links causes messages to not show up in board lists as having been read. Mostly likely because of the querystring differences between Previous/Next links and the URL's actually used in the Board list. I imagine we'll have to ditch the querystrings (past messageid) and go with hidden form fields.
The Ignore function works just fine, to my knowledge, and doesn't need any attention.
The message-fetching proc simply (what an abuse of the word!) needs to be modified to take ignore status, ignore types and message authors and recipients into account when determining the previous and next message id's to send back with the existing message.
