Sort ads within Category
In Classipress, ads are sorted by showing the most recent listings first.
What I would like is that for a specific category, ads are sorted alphabetically by title. Where can I make this change to say if Category x is selected, ads are then shown with alphabetical sort? For all other categories, I want the sort to stay the same (latest listings first).
Can anyone point me at where this code needs to be changed?
Thanks in advance
