Please read the LQ Rules about text-speak, and also the "Question Guidelines" and "How to ask a smart question" links in my posting signature.

We have NO IDEA what you're talking about, and unless you ask a clear question and provide details, there's no way anyone, anywhere, will be able to help you. What do you mean by "userdomain"?? Add it WHERE? How??? Also, please be aware that this sounds very much like a homework question...
