- With the details of your background in IT (or a link to it)
- With the details of your background in testing software (if any)
- With basic details of what you can offer testing for (product/operating system)
- Including how much time you think you can dedicate to this
I'm not going to assume anyone has the time for this unless they themselves indicate this and volunteer for this task.
Becoming a beta tester is a responsibility, takes time to do properly, and requires regular attention as well as regular feedback&communication (even if just nothing to report, still report the "nothing", and letting us know when you have to take a temporary or permanent leave from it again) and a long-term thing -- it's not just about getting early access or do-it-once-be-privileged-forever.
Communication with beta testers is mainly done through this very forum in private boards, to keep things organized in an easily-accessible way.
