DC, I think the issue was you put 2 and 2 together and got 5.

All that was suggested was a map people could put thier location on, nobody mentioned anything about it being their precise address. Lee suggested the auto location thing that apparently would take the location you've entered on here (I've not bothered even looking at it!) and put it on a map.
The only person to mention IP addresses was you.

As for forum security, vB is one of the better packages, however nothing is ever perfect and hackers always find new loopholes.
