Thanks John, I found the button but couldn't input to the calendar online. The idea is that we can list our names online under specific days and see in advance how many people are likely to attend to try and avoid instances where there are few/no volunteers as sometimes happens now. Some of us can then do an extra day or change days to fill the gap. Is this possible?
I think the teething problem with the new calendar should now be sorted. If you go to the introduction page and follow the instructions you should be able to use it as intended. Thank you George and Marion and Eileen for letting me know that something was wrong.
