Can I find out someone's Ip Address

[witchdct]

Hello, I am a manager of an msn group. I have banned a member from the group and this person has been able to apply again using a different log in name. I would like to be able to look at people's ip address before I accept them into my group. Is there a way to do this?
Thanks for your help,

Unfortunately even that won't stop someone who is determined to do this. All they have to do is apply from a different computer and then access from anyother one they want in the future. Have you tried asking MSN tech for help with this?
