Hi directory masters, looking for a script that comes with pre-populated category fields, in other words the most common categories already in place rather than having to create them, looking at IndexU with favor at present, your advice, thank you
For most scripts there are category dumps where you can easily prepopulate the categories. Here is a category dump for phpLD.
You can actually populate any directory script with categories if there is a SQL dump available for it.
Just note that when many people use the same category structure, the result can be many sites being the same, and getting some penalties related to duplicate content. This can especially be a problem when they have a large number of stub pages. Then you have duplicate content plus skinny content. Not a good mix.
