Okay, so I felt a little guilty about letting the bug creep in, so I have pushed through a new change - the ability to see a map of where visitors are from!
This is one of the items from the first phase of development for the non-anonymous user experience, and will play a big role in one of the second phase developments.
The call back facility will soon have the IP address information - its going to take a little bit of work to do to refactor a couple of bits, but it should be done in the next couple of days or so!
Oh, and all the logged visits have been updated with the geo IP details, so, enjoy! :)
