I tend to have multiple browser windows or browser tabs open, and return to those periodically. Whether I had read all of the threads or not, I had at least seen the message titles, and wanted them all "yellow" (old version of color flag); I would exit the forums, just to the AT Home page in the particular frome for the forum, and then re-enter, and all threads through the newest one that I had looked at would all be flagged yellow. I liked that, because sometimes the message titles seem repetitive, and I don't know where I left off . .
