The number following View posts since your last visit is not refreshing after every visit; just seems to be counting the new posts since my first visit to the new site.
I really like that idea though!! 
Actually what it appears to be counting is the number of posts since the user last logged off. I suppose the counter doesn’t reset for you because you are leaving the site while still logged in.
MuaHAhAhAhA… 
You are correct, sir. Kind of annoying though… Is there any automatic logout after a certain period of time? Or do I need to logout and login everytime I check the site? (My computer’s always connected to the internet…)
