Using form based entry when creating pages

Hi

Apologies if this has been asked elsewhere, but I can’t see a post which answers my question.

We are about to develop a website for a local U3A, an association which provides group activities for its members. We want some way to allow group leaders to enter details of their own groups in a standard format.

I think there must be a way to set up a specific page template which has a form embedded, for them to enter details such as group name, meeting dates. contact details, etc. All I seem to be able to find are forms for visitors to the site to complete, not forms to use when creating pages.

Can somebody point me in the right direction please?

Thanks

Ian
