On making something official it's a bit too early I think. I have a non-formal "go" from aklis on #trisquel-dev which - at least for me - is enough at the moment. As soon as we have some things to be published I'd come back to Quidam to get it approved.
I started a wiki page to collect everything. Feel free to dump in anything that comes up your minds, guys!
