We're really sorry you're having creating an account. Normally this process just works, but sometimes people have reported to us that they are unable to create an account on our sign up form here:

​
Please note that you don't need to use our sign up form to create an account, before you buy any books or courses on Leanpub!

When you complete your first purchase on Leanpub, we automatically create a new account for you, so you can access your purchases any time in your Leanpub library, and get updates to your books and courses, and add any new purchases to the same account so all your purchases are in one place, etc.

Even though there may be a bug with our sign up form, everything should just work when you try to complete the purchase!
