Is there any way to show in every post, not just the poster's username, but also an I.D. number that is based off of the user's IP Address? I know this is tricky, since most of us have dynamic IP addresses, and some of us use more than 1 pc in more than 1 location, and we don't want to put spyware on a member's pc, but there has to be SOME way to cut down on people making multiple usernames to use on this forum.
At least it would cut down on the quantity of these instances since it would catch the people who log in and out of multiple usernames in the same day. It would be too much hassle to consistently try and beat this or a similar system, but again it would be alot of hassle to implement as well.
