Doing the thread group change you propose is possible, and you are correct it is the council that should decide if that is necessary. As there has been two opposing priposals on how to proceed I feel that a decision is needed to determine the action.

The current (remaining?) council has not met for some time, even though I have now and then tried to rouse people by email. It seems there is so much other things that have priority.
There would be need to arrange election of new council and new board so things could be started rolling again.
