I only just made out what you meant if you meant 'can you sign somebody else up for Facebook on your computer if they don't know how' then the answer is yes you can create an account for them on a computer that they won't use as long as you know their preferred email
Hit the "account" button in the upper right hand corner and click "logout". Then have her login to her account.
To sign into Facebook, first make sure no one else is logged into the computer. Then enter the email address associated with the account, user name or mobile phone number in the user field. Then enter the password and click login.
Use a computer or mobile phone (with Internet access), then type in Facebook.com. You will get a Facebook sign in page which will ask for your user name and password or for your information to set up an account.
A Facebook account is no longer required to sign in on Answers.com.
to do this just type facebook in the google bar at the top and then a result should say facebook login.Also it will say sign up and if you want to have a facebook just click SIGN UP.
Restart your computer.
At the moment it doesn't cost anything to sign up for facebook.
