You posted something to the Internet. Whatever you posted is now in the public domain. That's just a part of posting on the Internet: whatever you post will be around for as long as the service hosting it is. Some services allow you delete what you've posted and remove your account; some don't. You need to take that into account when posting.
Easy guys. My intention was only remove my account. Not what I posted. And not cause nobody answer my question, just cause I won't be using this forum anymore. After this kind of messages, gave me more reason to leave. Thanks.
