How to get a facebook ID code from a username?

[Marina Wolff]

So I run two pages on Facebook, and people have been asking me to do S4S. And it's all good, until one person asked me to do it, but when I went on her page, she didn't have the Id code or link code in the about box. And I thought ok, i'll just get it from the link in my address box, but she had a username address like: http://www.facebook.com/username (just say it's that). I tried @[username:0] like you do for a normal code, and then i tried @[http://www.facebook.com/username:0] but that didn't work either! So now i'm wonder how do people make link/id codes from facebook usernames?

Facebook sucks. Don't use it. Spend your time doing something useful to yourself !!
