If you applied to beta test in the SimXperience Owners Club forum, and the email address you used on your account is valid, you will receive an email inviting you to the private beta testing forum where we'll distribute the software and discuss issues, ideas, etc.
The official Sim Commander 4 is scheduled for public release in early September.
This new software contains a large number of innovative new features and capabilities. I'll be taking advantage of this new developers blog to share these with you over the course of the next few weeks.
Special thanks to those who offered to test and provide feedback!
