If you'd like to create a Sonlet account but don't want to go through the hassle of creating and remembering a new username/password for the site, you can use the "Login with Facebook" feature, which allows you to login to Sonlet without typing your username/password as long as you're currently logged in to Facebook.  Note that using Facebook for login is not required, it's simply provided as a convenience for those that prefer it.

Simply go to Sonlet.com, and sign up for an account. Click Sign Up in the upper right corner of the Sonlet screen. 

Create an account using your Facebook login by clicking the blue Facebook login button.  This will create an account with a username, but no password.  You will use your Facebook login to login to your account. 

If you would like a Consultant account, you will see this at the top of your new account screen:

Click to Enable Now, and your account will be converted to a Consultant account. If you would like your account to remain a Customer account, click Dismiss. All Customer accounts are free.

And that's it!  When you visit the site in the future you can simply click the Facebook "Log In" button on the login page and you'll be immediately logged in.
