Here’s a sample Journal Entry
Creation of a page with a name that ends in “Journal” will automatically cause a Journal Entry form to appear on the page. It’s a little tricky because the form doesn’t show up until after you have saved the page for the first time (you don’t have to do anything - just save it), but once it’s set up, it’s very convenient. And since you can have any number of pages named “SomethingJournal”, you can create several of them to use for tracking multiple projects and so forth.
The form itself isn’t visible to visitors who haven’t used the edit password - those visitors can only see the journal entries.
