417886 Custom wordpress login redirct

I have a wordpress site set up. I want people to be able to sign up for an account, then be redirected to their own custom page. The page would show a listing of files in a folder on the server named after the name used during sign up. For example: I make an account with the name John Doe, a folder is created on the server named John-Doe, i am then redirected to my custom page with a list of files in my folder. Anyone with FTP access will then upload files to the folder that can only be seen by John Doe.
