Beta testing really isnt that hard, Unless you're doing like, Windows or something, in which case they give you instructions to test certain things.
I've been a Beta Tester of Plus! since its Plus! 2 Alpha (ahh...how I remember getting so excited when it moved from "Alpha" to "Beta"). At that time, Plus! was an undesigned machine with no icon
, how it has grown.
Anyway, Beta testing is VERY easy, it mostly just requires constant usage of the product. And sometimes patience.
