Not sure why you think OSCAR needs it own area? Does it exist outside of the existing categories: software, electronics, mechanics, constructions, videos and misc?
Ah - but you want a more focused view on OSCAR so that it is more self contained - right. Well surely thats easy - create a forum of your own
. Go completely open source via sourceforge (which was my suggestion to start with). Either its a part of SoR (warts and all) or it isn't - in which case "why would Admin want to host it" - but then I'm putting words in his mouth.
So either its a part of SoR or it isn't. And I mean that in terms of us all learning from posts in ANY thread. For those who dont want 'yet another forum to keep checking' then also consider those of us who 'don't want to register for OSCAR' - it works both ways. So convenience is not a reason for doing it either way.
OSCAR and non-OSCAR people can still learn from each other. IMHO you are still trying to build a standard - unless you have say 5 modules already that prove the multi slave/master I2C. So why not have one person who maintains a Member Tutorial on OSCAR that keeps all standards and module building tasks up to date. You don't need the history so having one member page that summarises and cross refs the forum posts would make sense. Of course you could just do this in sourceforge anyway.
