I'm using Showcase and it creates a new associated discussion thread every time a Showcase Item is created and these type of threads will be included in the "New Posts" list (both in the sidebar and the /find-new/post page). What I want is to exclude these threads from the list. I've checked the database table, in the xf_thread table, I found that the discussion_type field value is 'showcase' for these threads. My question is where to modify the sql query or is there any other means to filter the value of this field? Thanks.
