Just logged on here ~ 1/2 an hour ago at home after having been on here a couple of times at work and apart from the regular occurence of having to re log in at work I noticed something strange just now
I looked at the post about the Motorcycle Ownership Survey, scrolled to the bottom and thought I have read this already and yet the last post on the main page after I hit "view new posts" was suposed to be at 7.12PM by JoelMikel and yes it is but on the actual post it has a time of 5.40AM which would be why I had seen it before

It updates the time stamp for the last vote, not necessarily the last post.
