I've got two groups. I've got two forums belonging to each group. I've got a panel set up to display a custom view of forum topics that are defaulted to the group id, so that when given the group id arg in the url it shows the forum topics that belong to that group.
The problem is, I now want a menu item on each group page which says 'forum' which points to the forum view with a group id argument which causes the display of only related forum topics.
