Past and future programme

Starting with the AUTUMN term, we abandoned monthly payments at the meeting.

We requested a £10 subscription to cover the first term. The reason was simple: members sign up to join a group but do not attend meetings. We must cover our costs, and the room hire is £60 monthly. Therefore, at £2 per member attending, we need a minimum of 30 attendees. We immediately reduced from over 70 to 59 registered members. Asking for a subscription up front weeded out around 10 non-attenders.

Paving our way. We need committed members

All went well, a healthy surplus at DEC 31 meant NO SPRING termly subscription

However - we are now in the third - Summer - term

It is now time to ask for your termly subscription of £10. You can pay in cash on the day.or you can pay online by BACS - which we much prefer. Paying online could not be simpler. Please make your £10 payment to CAF Bank.

Remember that this is YOUR GROUP. Please consider joining our little management team for the interest group. You can contact either Ray or John.

We welcome anyone who is prepared to help put together the group's future programme of talks, discussions, visits and demonstrations.

The 2022 Sci & Tech questionnaire - results analysed

We asked our interest group members what they liked or disliked about our presentations; where we met and more. As a result we have a great deal of help in managing the group - when and where we meet; how often; what subjects are interesting, etc.

Brainstormed ideas - our source list

Check out the list of 252 items. If you can find one to interest you we would be delighted to present it as a topic - or you could do it yourself!

Past presentations

The group has met since about 2005, so we have managed to keep a number of past presentations as PDF files. To find out more click the button. Where past presentations call up a video it cannot be shown in the PDF file. But we can always find the original you are interested.
