Re: Internet Explorer and forum points.
I'm not an IE user, so I can't speak with authority, but as I understand it the page tabs are also content security indicators in recent versions (all secure/https, mixed content, all unsecure/http, third-party elements/cookies, that sort of thing). And the post count (along with the credits, when they're visible on the site) can lag the actual count by a bit, particularly when you've just posted and remain on the same thread. (If they get the credit system up and running again, you also need to be aware of how credits work in individual forums here -- some are "no credit", some are "extra credit", and the rate of accumulation depends on the user group you belong to.)
