I followed the tutorial Calendars for Organic Groups - A simple tutorial for D6, and successfully created a calendar for every group in my site showing its events. I also managed to show the calendar as a tab in every group homepage using the path
Now I want to create a second calendar page, shown as a tab in every user profile page, which will provide the user information about all the events that are registered in the groups the user is a member of. I created a second view, and configured it to show all the events of the site.
How can I limit this view to only show the events from all the groups? How can I add its page as a tab in every user profile? Is there a way to limit the access to this tab to only the user that owns the profile?
