I would like if a classifieds component can be created within the ossn. Members would be able to engage users and visitors, transact business as unique as OLX and others.
why not create a group and link in ebay, far easyer
Not that easy tasks as Bansh said, its like creating a new CMS. Most of people think its easy stuff but when you think about the backend and handling payments, errors , disputes, etc you'll find out its difficult task.
someone literally just asked practically the same question: https://www.opensource-socialnetwork.org/discussion/view/4254/is-there-a-way-to-add-a-marketplace-component-to-the-fakebook-theme
at least make some effort to search and see if it's been answered before, because this is asked about a lot. it would be a very time consuming job and would likely be expensive if you wanted to hire a developer to make a component for that.
Due to the many requests in the past for additonal features and components we have decided to develope a premium version. Features like Hashtags, Videos, Polls, Events, Stories, Link Preview, etc included in it.
