A full-featured Community Forum module for public and members-only categorised discussions. The UNA Discussions app is a forum & discussions module that can turn your website into a lively conversation hub. Interaction with other UNA features means you can comment on discussions, react to them, categorise them, embed links, pics and videos, embed discussions into groups or apply hashtags using Channels. The Discussion Module has customisable settings and the option to enable Category Visibility (managed via the Permissions Module) so that certain Discussions can only be viewed by designated user levels.
As a Reddit Alternative
Reddit is a social sharing website that markets itself as the 'front page of the internet.' With simple configuration you can create a member site just like Reddit, allowing your users to create and respond to discussions - perhaps your Discussions Forum will be centred around a single topic, a series of topics, or users can create their own groups and have discussions around whatever topic is of interest to them.
As a Quora Alternative
Quora is an elaborate forum where users can post questions around any topic and other users can answer them, with all users voting upon the best and most useful responses, which are then featured for future users. UNA Discussions along with Upvotes and Downvotes can give similar functionality, giving you the infrastructure to create your own question and answer forum.
