What Features Should You Look for in Forum Software?

Forums are as old as the web itself. And forum features have evolved and changed significantly since the days of the first online bulletin boards.  

As such, navigating the large feature sets of modern apps is challenging. And it’s usually a good idea to figure out what you need as an absolute requirement and work from there. 

Here are the main features to look for when evaluating forum software: 

  • Basic functionality – Basic functionality encompasses user profiles, flexible hierarchy controls (categories, sub-forums, threads, etc.), admin permissions, WYSIWYG post editor that supports rich media, and so on.  
  • Engagement tools – Common engagement tools include personalized homepages, intelligent feeds, and member emails.
  • Integrations – Integrations allow you to sync your forum with your tech stack. A Zapier integration is a big plus. 
  • White-label branding – The best apps fit seamlessly with the existing look and feel of your site. 
  • Developer tools – Forums that provide access to APIs and a software developer kit (SDK) give you complete control over your forum’s functionality. 

What’s the Difference Between Modern and New Forum Software?

The line between “modern” and “old” forum software isn’t a clear one. Most traditional platforms have released new versions to cater to changing user habits. 

Generally speaking, you have to run traditional forum software on your own servers. Ongoing maintenance, updates, database management, and so on are entirely your responsibility. SEO and user engagement features, like regular “best of” emails that tell members about new content, are also often lacking in older apps.

Modern forum software requires little if any technical expertise. It is usually sold as a software-as-a-service (SaaS) package, meaning it is hosted and maintained by the provider. Modern features, like mobile responsiveness, smart feeds, and third-party integrations, are usually a given.

The first step to finding an optimal solution is to identify your needs clearly. Do you want to have private groups, for example? Do you prefer question-and-answer-style message boards? Are user groups and segments important? Do you need to integrate with a content management system (CMS) like WordPress?

Once you have answered questions like these, you’ll be much better placed to find a solution that delivers for your community and business.

Finally, if you’re looking for a hosted, modern solution, PeerBoard offers a “forever free” fully-hosted plan with an array of modern features. You can try the platform with no strings attached and you’ll never be forced to upgrade.
