I'm sorry to hear you have resigned. In the days when I started as a councillor the local paper would often send a reporter and it was relatively easy to get comments into the local paper. I'm not sure we have a local paper anymore. In any event a resignation would often get maximum publicity.
I soon came to the decision that resigning was a rather short term effect, and it would have been better not to resign and continue the fight from within. The next time a vacancy notice goes up, grab your 10 signatures (actually you need 15 to ensure you have 10 registered electors) then go for a full election. That way you can air your points of view. (Oh wait, there is now a new vacancy:-)
