Freelance job

Hi,

I have a website (a CodeIgniter script I bough from CodeCanyon that has user management, Facebook login, among other features) and I want that when someone register an account, they also be registered to a WordPress blog and to another PHP script so people will not have to register again and they will be able to use the same login details in the three websites.

I want that WordPress import avatars, usernames, emails and passwords and I want that the another PHP script import genders besides that data. I also want that users only be able to create/edit their accounts from the CI website.

Thanks.
