About this Course
It's time to dig in and build something big. In this course, we're going to take the tools we've learned, Flask, Peewee, and Python itself, and build a small social network. We'll have user registration, user authentication, strongly hashed passwords, form validation, and more.
What you'll learn
- User registration and authentication
- Password hashing
- Form validation
- Joins
Making Strong Users
We won't get far in our social application with out users. Let's make sure their passwords are stored correctly and strongly, too.

Takin' Names
Users need a way to sign up and sign in to our site. We'll need to validate their information, create our model instances, and store their session information. Luckily, we have a few handy libraries to do a lot of that for us!

Broadcasting
Our app needs messages posted by the users. Let's give them a model, a form, and the views necessary so they can tell the world what they're up to.
10 stepsHow to Win Friends
The final ingredient in any social site is the ability to follow people. We'll need to add a new model, a couple of views, and tweak a template or two. We'll also want to change a query or two to get the full social experience.

Extra Credit
Some other ideas for extending this app are:
- Add a form and view to allow users to change their username, email address, and password.
- Allow users to repost or respond to updates in a linked method. You'd probably want to start by adding a foreign key to
