link calendars to avoid conflicts
You should be able to link calendars to avoid conflicts between related projects.
Could we get clarification on this one; we don't fully understand this request. We have a global calendar of all projects that you can subscribe to and when you create an event, you click the "check attendee availability" button to make sure that time slot is open for all attendees across all projects.
This is essential!
You can do 2 things here. First, you can click "check availability" when creating an event to see if you have that time slot booked on any other project. Also, you can see all projects on the global calendar. Go to your main Projects page and then click the calendar icon to see events across all projects. Does that solve your issues?
Really what I meant was to be able to see other projects in other project's calendar.
