I that in a nutshell shows how inadequately equipped/staffed/organized the "Council" is (sorry for using quotation marks but I swear I can't take that 'organization' seriously).

If you time after time after time do something and you don't get any reaction or response - then why keep doing it in the same way?

Arrange sit-downs (virtual/physical with Nokia representatives), ask for key contacts that you can go through and set expectations in terms of what you can expect from them, arrange for petitions/signatures for main issues, use other channels (gizmodo/techcrunch, etc, etc) to let Nokia know about that there are things that needs to be fixed, etc, etc.

And if none of that, and other attempts doesn't work - then it is obvious that as a 'Council' you have no purpose and that your tag-line is useless and the whole thing should be phased out.

Sorry to be harsh but to have as a defense and reason for existence that you 'try but never get anything done' is very, very weak and it might just be time to man up and realize that Nokia does not take this 'body' seriously.
