Members of our community have mentioned using plugins such as
Twitterfeed or the
RSS Graffiti app to achieve auto posting to facebook, so it is possible to do. In your ClassiPress settings you can set it so that expired ads are sent back to draft mode (unpublished) from your site. In terms of other customizations, AppThemes does not offer customization services, however we do have a
certified partners page where you can find developers for hire. If you make contact directly with an outline of your requirements, they can provide a quote for the work. Thanks.
