Custom Post Type posts in Category pages in BuddyPress Daily

Hi

I've added a Custom Post Type to my BuddyPress site to store venues. It's named northings_directory.

Posts from this northings_directory Custom Post Type are showing in Search Results, but they do not show on Category pages (i.e. http://northings.com/category/galleries/ should show a number of posts from the Custom Post Type).

I'm using BuddyPress Daily as the template. Do I need to associate the new Custom Post Type with the Categories PHP page in the template?

Thanks
Marcus
