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 appear until after you have saved the page for the first time, 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 track individual projects and so forth.
