Tuesday Forums

Forums have a "current affairs" focus covering local events, politics, science, the environment and international events.

Sessions are held via Zoom typically on Tuesdays at 12:30 pm and run from February to early June and from mid-July to November.

There are two registration options:

* Pre-register for all talks during the year and you will automatically be sent Zoom login details each week, i.e. there will not be any need to register on a weekly basis. (Note: Those who pre-registered in 2025 will automatically be transferred to the 2026 Forums.)
* Register on a weekly basis for the Forums which interest you. Registration will open in the week preceding the talk and the details are advertised with each Forum.
