ok - i think this will come about naturally, if the developers are
permitted to interact freely with the free software community. that's
just been added this morning btw. if you disagree and have something
more specific in mind, please could you create a separate section that
i can drop into the proposal?

*lol* - you mean... they don't _have_ any?? that would be... shocking! :)

*sigh* :) ok. this may be true, but i need to put it a better way
:) would you be happy to throw some words together that can go
directly into the proposal?

i'm not on it for many reasons, the key personal one being that i
wasn't involved in the creation of linux-sunxi.org: i found out that
it existed several *months* after it was set up, so i'm still a bit
pissed at that. the key "professional" one is that it would be
another list with specific technical discussions and user-related
questions that would completely overwhelm my ability to manage the
other things going on.
