We don't want new users testing builds, generally we want experienced ones. Most of the functionality provided by new features is in response to mod requests and longstanding interest in having a new feature available. A new user isn't going to crack open FRED, say, and whip up a complicated scene using the camera code, or start writing new ship types in the tables.
A formalized testing team would be nice, but last time I tried that, we had about 10 people signing up and only 2 people actually made an effort to check the forum.
I think it'd be more interesting if somebody wrote a test mission...I was just thinking the other day that a G-mod like mission could be pretty fun to test in. You could use show-subtitle and is-key-pressed 1-4 for menus, or record pressed keys using scripting and use script-eval-num to check 0-9. Menus and interface might be easier with scripting too.
I'll include a script with my next build that'll let you get the numeric value of the numrow, numpad, and function keys that you can use from FRED.
