Hello Modx Community!
Are there any extras to create a community section for a website? This might include, user interactions such as message posts for questions and answers, networking, profiles, share files, etc…
Yes, forum, but could be done through an extra. The old extra was called “Discuss” and added forums directly into MODX. I used it in one site and it worked pretty well at the time. People have had success with VanillaForums (which I did, too), but don’t know if that is still a good option. Discourse seems popular at the moment, and there is an extra to create some integration: https://extras.modx.com/package/moddiscoursesso?version=1.0.0-pl
As far as I am aware Articles is not really usable at the moment, commenting and such use Quip which is not working properly. For anything similar I usually use collections and tagger which works well for everything but has no commenting feature.
I think for a proper forum integration Discourse is the best/ most powerful option.
