New Signup

[ebetron]

The goal of this FR is to simplify the Signup process.

This will be achieved by doing the following:

• Sign-up should only require first name, last name and email fields.

Other requirements:

• The signup page should have a brief summary about the platform and its purpose (copy is pending).
• Once the user submits the registration form, an automatic e-mail should be sent with a tutorial about the platform functionality and purpose.
