Don't forget to visit the Roadmap and Logs page that will give you the status of software, what are the new features, the known issues and what will be coming.
There are three PDF quick setup guides available: Net Device, Line Device, and Cage.
If you experience an issue with your In/Out device, first visit the troubleshooting page. Then fill the support form through the In/Out helpdesk.
If you don't own an In/Out and have a question, contact the In/Out team.
