Unless it has to to with others viewing MY posts, then I can wholeheartedly say it's a definite "NO" on that one, jbox.
I've been logged into BYOAC 4 times today for mebbe an hour or less total time, and I've always lost posts during the time during which I'm not only not logged in, but completely offline, and not even inside my house.
I've lost 1500+ thus far, and about 200 since the last time I was logged in.
