I wouldn't force the council to be a promotor of a specific project in maemo.org. Sure some project's worked on here are more visible than others and attract more attention, false conclusions and so on but adding an exception to include some named project to be catered doesn't solve anything. The council's tasks already include "Facilitation: making sure that one portion of the community knows what is going on in another " [0]. To me this already covers CSSU and no extra duties are needed. As for a techincal streering group (TSG) I think that's up for the project itself to setup if needed not for the larger community. To me CSSU is a project within the community not a project by the community.

Just my 0.02
