Following the reasons for wanting to build a Facebook-integrated app, we're going to need to define the user roles and associated rules for the two different instances of the app.

This is where things start to become a bit confusing!

Types of users entering directly from the site;

• AnonymousVisitor
• AnonymousUser
• RegisteredUser

An AnonymousVisitor is a visitor that's accessed the app, but we know absolutely nothing about.

An AnonymousUser is a visitor that's chosen an available username. The username is not stored, but will remain a unique identifier for the remainder of the session, to avoid conflicts in the application.

A RegisteredUser is a user that has decided that they enjoy the network and would like to further explore the other features and services. They will have the ability to reserve a username.

Types of users entering from the Facebook application;

• FacebookAnonymousVisitor
• FacebookVisitor
• FacebookUser
• RegisteredUser_Facebook

A FacebookAnonymousVisitor visits from Faceboook for the first time and will be immediately asked for permissions from the application.

A FacebookVisitor is a visitor that has given the application permission to access their details. The details are to be stored and the username temporarily reserved.

A FacebookUser, is a visitor from facebook that has chosen a username and is now using the app.
For seamless user experience, a returning facebook user will enter the chat immediately with their previously reserved username.

The RegisteredUser_Facebook user type is a visitor that has sucessfully signed up to the main site, but has also chosen to integrate with their Facebook account.

Pretty crazy eh? Believe me, blogging about this helps! lol
