I am using Classified Ads module which includes a new content type for classified ad. I've created a taxonomy vocabulary for classifed ads categories and so if I go to /classifeds/24 it lists all nodes for that specific taxonomy term (category). What I still don't understand after much research is how to hook into that "list" page. The hook_views_pre_view hook doesn't get me there, so if its not a view then what is it? It seems to me it would be like a "built in" type of view which is querying for nodes within a specific taxonomy term, though the hook_views_pre_view hook didn't get me there. I hope I explained myself clearly.
