This web site has a number of aims, among them:
You can send in your observations, comments, complaints, etc. by filling out the form on the Your Say page. As a rule, material you send in will be posted on this News & Views page.
You can read the issues pages and then use the material to send an e-mail to relevant members of the council (e.g. you can copy as much as you wish of the material into the e-mail form). Note that not all councillors have e-mail addresses, so you may have to contact them by snail mail or ask the ones you do contact to print out copies for the others.
A further thought.
The democratic process doesn't end at the ballot box. That's where it
begins. After the ballot is over, voters need to continue to take an
active part in what happens. Theirs is not just a passive role, putting
up with whatever decisions their representatives make. Indeed, those
elected need to know what the people think and feel if they are truly
to represent them. So, voters have an obligation and a duty to be a
continuing part of the democratic process, and to persist in putting
their ideas forward and in making their opinions and aspirations known
to those they've elected. That's what being a responsible adult means
in a democracy.
