How to register for the online service
If you've never played online, you'll need to register for the online service.
From the main menu, tap or click "Multiplayer".
A window will appear:
Click "Register" here. You will be brought to a web form:
Fill it in with your desired user name (every player will see that), your desired password and your e-mail address,
then make sure you agree to the terms and conditions of the service and tap/click the SEND button.
You will receive an e-mail message (check your spam folder as well!) with a link to confirm the registration.
Sometimes the e-mail takes up to 24 hours, but, in 99% of the cases, it just takes few minutes.
Click on the link in the e-mail message and you're ready for your first login (click for more info on that).
