Odd bug, FYI,
ON my favorites page I have cOUSIN SHORTY showing 3 new posts as of today, but when I link to his member page, not only are there not three new posts, but the posts of his that I read last week where he re-challenged Jenna to a stock picking contest were gone.
I have had this happen with other of my membermarks (not the deleting part), where it will suddenly show that someone has a new post, but as far as I can tell there is nothing new.
