Why should I register

The SIM Dashboard Community allows users to share designs with others easily. Downloading these Designs is possible without registration either directly in the app or by browsing the website

So why should I register? Registration is required if you want to share a design with the community, because with your account you are able to publish updates of this design later on. Whenever you improve your Design you can publish an update and tell the users what you have changed. Without registration it would be much harder to ensure that only the original author can update his designs.
