UltimateWB Full includes the built-in Classifieds app (and Listings app which is for more of a yellow pages directory).
Currently it does not include encrypted email addresses like craigslist uses to not show the users' emails, but it does incorporate Private Messaging, so that members can communicate directly on your website without disclosing their contact info. Also, you can allow commenting/rating on each ad (and also allow posters to turn off commenting if you want).
UltimateWB Full 4.4 which is planned to be released soon actually includes the distance search in the filter/search/advanced search tools for the Classifieds app and Listings app. You can customize the distance options, as well as whether to display it in km or miles or both. Purchasing the software at any time will include this upgrade, as each software license purchase includes 1 year free of any software updates released. This upgrade is actually already available for testing/viewing on our UltimateWB Full demos at https://www.ultimatewb.com/demolinks .
From the Classifieds app you can navigate into the categories you have created. You can include a top filter menu to filter through ad types, country, state, city, and by distance. These options are also searchable in the search/advanced search tools if you choose to include those in your website. Search/advanced search tools may also include search by keyword, in the title, tags, and/or description (with option all allow user to choose which to search in/search in all). The advanced search tool may include any custom fields that you have created on a category/type basis that you have marked as searchable. These custom fields can be configured on a category/type basis, and when marked as searchable, will display on the advanced search form when that category/type is chosen. Additionally, you can add a sort menu at the top to sort through ads displayed in a catgory by name, price, date posted, date ad expires, type, likes, views, comments, and distance too, both ascending and descending order.
There are lots of customization options!
