Scrolls through the page and clicks on a section edit link, and tells me he expects there is a similar link at the top. Eventually he finds the tab at the top and quickly finds the typo and fixes it. He doesn't enter an edit summary and saves the page.
Adding a sentence
He clicks the edit tab at the top, and scrolls through the text to find the end of the first paragraph. He clicks back to the page to check what the end of the paragraph is, clicks back to the edit mode and adds the sentence.
Adding an external link
He clicks the correct section edit link and copies the syntax of the existing list of links.
Adding a reference
Again, he clicks the edit tab at the top. He learns about the syntax by clicking back and forth between the article and the edit page. He incorrectly copies the syntax of the link, although he recognises this to be some kind of source code with tags. He recognises his mistake and he tells me he would now check out the syntax by example, but it isn't really clear to him now.
Changing population count
He finds the edit tab at the top again. First he changes the count in the sentence. While doing this, he notices the number in the template and changes this too, and saves the page.
