We just released the classified theme version 5.3! We managed to bring it up to wordpress 3.0 standards.
The list of the new features is not ready yet, as the list is long and i want to structure it very well to present it to you.
The most important thing you must know about the new version is that along with wordpress 3.0, ads have their custom type, thanks to wordpress custom post types. Pictures are kept in wordpress media library and attached to each ad.
More info will come in next days.
