When you subscribe to a calendar in Gcal, you can globally set default reminders for the particular feed in settings. But can you change those reminder settings for individual events in the feed? I find that I can't . I keep getting "failed to save changes" (or something like that). Is this just not possible in Gcal? And if not, is there another online calendar that does allow this? Thanks.
You could copy an individual event to one of your calendars and set the event reminder on that. If it clutters your calendar too much, you might create a special calendar ("Reminders") just for that that you don't display with your other calendars.
