It works, and more importantly, it's simple.
1. Log on to your garage.
2. Open this OP in another tab.
3. Click on a name in the OP to go to that person's garage.
4. At the top left below "Short direct url to this page" is a button marked "Favorite: Yes/No"
5. Clicking yes puts the driver's name into a list on your page. You may have to refresh your page to see it.
Brilliant!
