Re signing up on poker sites to get rake back

[Teldar]

I have a quick question. I didnt sign up through any affliates at Party & UltimateBet, so I dont get any rakeback (I know, I'm an idiot). Here is my question. Some people have suggested that you sign up again using an alias. How do you recommend I do that? Does that mean I need to use another person in my family to sign up? Can I re-sign up using my name and a different address? What has been people's experience doing this? Thanks for your help.
