You lost your cookies!
Stanford & Co. have been cleaning up the index frame a bit. There is a thread on this elsewhere on the page.
Some felt that "BJ Misc" was a misnomer, since it is actually the primary free page.
Since the title of the page is changed, it no longer recognizes the "cookie" that contained your preferences. Also, it is now a "new" page, so it doesn't show up in your history file - so no "new message" flags.
Not to worry. When you return to the "page formerly known as BJ misc," your "new" tags will return.
