Not sure I understand the correlation between a contact form plugin and a directory plugin
My observation was meant to be a constructive criticism Steven.
If you were to take a look at a contact plugin by the name Fast Secure Contact Form you would see what I mean by easy creation of Custom Fields.
In my simple mind it would seem that the classifieds could use a system like this to transfer the fields into the frontend template, but as I say I have a very simple view of the processes involved and it is probably more complex than I can see.
You have a great plugin here Steven and more to the point GREAT SUPPORT, but at this point it is not going to be suitable for a novice coder with limited time like myself.
I will be back in the future when I have more time as I am always building directory and classified sites for clients and my own purposes
All The Best
