Classified ads form Customize?

hello, I am newbie to Dolphin .

 [join form] could be customized  in the admin panel , but how to customize the classified ads form ?

I think housing ads is different  job ads  ,and so on.

Different ads category should have its own form.

and I also want  to add a [station] field to the classified ads form ,how could I do? thank you very much.

Change post Ads form you can just in BxDolClassifieds.php class

function PrintPostAdForm( $arrErr = NULL ) {

change categories you able in admin side of Ads

Just understand how Ads works, and you will able add here another one field

I will have a try ,thanks a lot.
