It's easy to create an account in Milkymap. You can signup and fill in your details with a Satellite subscription. Below you will find an example of the sign up screen. You can try it for 14 days for free, with all the features included, cool huh?
Once signed up, you can start using Milkymap immediately. You can upgrade to a paid subscription at any time, also after the 14-day trial.
Good luck with Milkymapping! :-)
