I remember back to when I first wanted to be involved with testing, and reading through the links I think I felt a little overwhelmed with it all.
As I’m typing this I see @Calie has mentioned what I was going to suggest - a Quick Start Guide that highlights the main bits and pieces in high level bullet point, what is needed to qualify as such and that it takes time.
Links to more in depth details and info at the end for people that want to be involved, making it clear that it needs to be read, and any questions to be asked through Sex Toy Tester - Chit-Chat where established testers can help guide you
Read through further and realized I’m not actually offering anything new, but I’ve typed it now so will post
