If not, would it be possible to incorporate some kind of read/unread marker which is not cleared out when logging off?
It took a few hours (and some users may have noticed about 15 minutes of "downtime" while I scrambled to find a bug I published), but it's working now. New message flags will only be removed when you open a topic. Logging out either manually or automatically (a session timeout occurs after 1 hour if you don't click the "Log out" link) will not change the status of the flags as it more-or-less did before.
Note that since the software can't determine which messages you've read after opening the topic, it assumes you have read them all. Essentially, there is no change in how this works now compared to how it used to work during a single session. The "new message" flag is cleared when you open the topic, and is reset the moment someone adds a new message to it.
