The technology used to create and manage online communities includes social media platforms, forum software, and content management systems (CMS). Tools like Facebook, Reddit, and Discord enable user interactions, sharing, and discussions centered around common interests. Forums may employ software like phpBB or Discourse for structured communication, while CMSs like WordPress facilitate content sharing and community engagement. Additionally, mobile applications and web design play critical roles in enhancing user experience and fostering connections among community members. These platforms support asynchronous communication, making it easy for users to participate anytime.
