Hey! I see that Simon has fixed the little loophole that I've pointed to in the past on how to get someone's IP address. Not too long ago, someone could embed a picture into their post(like a blank, 1 pixel transparent gif file), say on a home http server, and then correlate the timestamp with the referring URL in the httpd logs. Now when you reply to a thread, any html <img> tags are stripped out of the replies. You can still see the IP's of the people who browse, but it is now much harder and requires a little more detective work to find info on a specific poster. It's still possible, but very difficult to do.
Thanks Simon for incorporating that change! It will go a long way in helping to keep the anonymity around here for those who need it.
Oh, and for those who are wondering what that little gif file looks like, it is right here between the arrows --->
