The site I'm working on will have many OG groups, each with a list of topics relevant to their members. I would like to show content to the logged in user that is about their group's relevant topics.
I started by creating a vocabulary (Topic) and two content types (Group and Post). Group and Post both have a term reference field that lists Topic terms (groups have topics that are relevant to the group, and posts have topics about which they're written).
How can I create a view that shows only posts with at least one Topic term in common with the logged in user's group's Topic list?
