If I change the title of an article, does that change the link of the page?

Hi Hannah , thanks for your question! Yes, changing the title of an article will change the last part of the link, called the "slug." However you won't need to notify people of the change because the old links to the article will still work. This is because the system always finds the article based on the 6-character code in the URL that precedes the slug. This code never changes.
