So I started getting a graphic with the text CI6728 in between the first and second posts. Happens on a couple PCs. I'm running FF with adblocker and ghostery. It seems to be innocuous but just wondering what it is. Don't remember seeing it before.

It has been there for two to three days on my computer. No ads just a blank and always between the OP and the first reply. No clue.

I see it now, thanks alot. CI6728...over.

You're welcome...

Uh oh.

I searched the interweb for CI6728 and found this ...
