Thanks a lot to Roy and Nigel for your replies. I’d looked for options on the ‘Privacy’ and ‘Hide & Show’ tabs of the ‘Family Trees’ management page but I didn’t think of looking at Modules -> Menus. Works fine now.
Thanks also to Nigel for the explanation of how to create multiple Simpl_pages, which seems fairly straightforward, and quite flexible. I use Xemacs on Mac for my text editor, and living in France I’ve got used to dealing with problems of accents! There are always files and folders which need to be copied when upgrading (the data folder for example), so I’ll try to remember to include the copies of the Simpl_pages folders.
Thanks again for your help.
