Hey Lisa Thanks so much for reaching out! Good news is, a Card’s URL actually shouldn’t be affected after a title change as it uses an ID to identify the Card, regardless of the title. So - if you bookmark a Card or hyperlinked to a URL prior to the changes you should always be able to get to it even if the title changes...

After the Card is loaded, the URL will change to the right one for the current title. The trick is that Guru utilizes the ID that's in the middle of the URL, or, the "slug", this allows us to look up the Card regardless of the title.
