Can I get someone's ip addy off an online poker site without corresponding to any emails etc...

First, its not a good idea to piggy back your question on another thread. To avoid confusion your post has been moved to another thread.

Second, if you own the site you should be able to get the IP of users. If you don't then no. Even if you have the IP, you can't find out anything more than the ISP that issued the IP.
