Well ...that bit of background cinema-graphicesque flashback helps...
then we most definitely need you ...
don't know how I missed the work you were doing here back-in-the-day...
dump that buncha dehydrated figs from Debian...they got plenty of people helping them..get on the GA ...and spend your time meaningfully with the crowd who will shout "huzzahs!" every time you come up with something good...well..I will...at least...ok...maybe once...but ...you'll at least get 1 "huzzah!" .

Anyway...
Far as the safeguards with the GA go...
with human nature....better safe than sorry...
I do think meeting you halfway and agreeing that new tmo people should be informed ..
but participating?..mmmm..nope...like handing matches to a kid...better to give them a coffee warming plate they can't burn themselves on in the form of released logs and transcripts....
at least until those new folks have their maemo sea-legs under themselves...
if they sign up for the GA and are screened and accepted (I know that sounds elitist ...but it is a sane safeguard) then great.
But...I've helped number of new people who were brand new to the device line (and it is great to do..gives fresh perspective, insight, a good grasp to explain things in layman's terms too)...some new ones who even thought (at the time) they had a good grasp of even the old models... and ...no offense intended ..nor any ill of any sort implied...I don't think any of them (excepting a couple) were...at the time...ready or able to understand much past what I threw at them...to help them get up and running with their devices...had to use the plainest of language even...and I wouldn't suggest they join up to the GA until they understood the basics of their devices 1st ...
I don't say any of this to diminish new folks in any way...it's just so much for them to absorb ...to take in..how to utilize their devices properly to just become competent users and get the most out of their devices...throwing them into meetings because ...they're allowed... wouldn't be helpful. I think it would be overwhelming for the majority of new members.
Also a join the GA button sounds like a very good idea...
a visible-presence-initiative like that would help ...If something isn't easily seen...it tends to remain unknown...
