Sure, as a council member I promote CSSU to parties outside maemo.org. I wouldn't call it PR because the general public hasn't much interest. But external collaboration with outside groups interested in FOSS on mobile devices, sure.

I've corrected the link in my post. To be more specific, the point I was trying to make is that someone called CSSU stable a joke. I empathize that merlin1991 felt compelled to respond to such a callous comment. I would like to organize internally and give better feedback to CSSU.
