To use the roller creation platform, you need to login with your user name. You can do it with this form.
If you don't have an user account yet, you can register as a user on the registration page.
If you only want to test our demo platform, you can use a username 'demo' and password '12345678'. The demo platform is similar to the actual platform, but in the demo you can't use your own images. The saved Rollers might also be deleted at any time.
