Stealing IP addresses

[Canuck]

Hi, I'm new to this forum and would like to know if it's possible for someone to "steal" the IP addy of another person in order to post on a forum using the other person's IP addy? Thank you for your responses.:)

First let me clarify that I do not want to do what I have asked the forum, but that I suspect someone else has been doing that elsewhere and wish to know if it's at all possible. Thanks again.

a backdoor/trojan horse will allow someone to use your computer that way. Also, if you have a wireless router another comp connecting through it would have the same ip address.

yea gordo is right, many trojans out there can do that, if the person is you, I recommend getting AVG free or something to scan for virus's
