Someone has shared a Google calendar with me, but I don't see it on my list of "Other calendars". What can I do?
On your Google calendar page, go to "Other calendars", and click on the little downward facing triangle thingie to the right (not the left). Choose "Settings" from the downward triangle menu. At the bottom of that page, you will see all of the calendars that you have access to, and you can check which ones you want to show up in your list.
