If you would like to give feedback on each presentation then your email address must be registered on our secure database.  Most of our members have already provided their email address which will enable them to use the Feedback form.

If we haven't got your email address or if it has changed then please use the Register form or inform us directly on

Once we have confirmed this, you can use the Feedback form after each lecture.   The feedback section usually remains open until the end of that month and you will be sent a reminder after each presentation.
