Over the last several years, a 107IST member created and shared Google Calendars (subscribable iCal calendars) for the Timbers, Thorns, and T2 schedules as an alternative to the FO calendars. Links to these have been shared both on Twitter and the 107IST Member Forums before, but now we're making the links and instructions easily accessible to everyone.
If you've subscribed to any of these calendars previously, no action is required--as matches are added or updated (think time changes, playoffs, next season, etc) any calendar to which you are subscribed updates automatically. These links and instructions shouldn't change from year to year--just set it and forget it! Not sure if you've subscribed previously? Check December 6th. If you have an event at 3:18 PM Pacific, you're already subscribed. Calendar URLs and directions below:
You should be able to add these calendars to anything that allows you to add an iCal subscription via URL.
If you want to copy events to your own calendar after subscribing:
Note that events copied to your own calendar will not update automatically (due to change in kickoff time, etc).
