EasySocial 4 has included a built-in Marketplaces support to allow users to place their classifieds. It's available for user, groups, events and pages. Just like the rest of the features in EasySocial, the Marketplaces has custom fields support and it is very extensible just like user profile, groups, pages and events. It is also has a very robust ACL system in place for you to define your desired access permission for each of the Marketplace categories.
