I was just exploring the possibility of creating curated collections (links or other materials) that users could create on their own, vote for individual list items, comment on and replenish other people’s collections (if the collection is open). The most basic examples of the successful implementation of this idea can be considered ProductHunt and HackerNews
So far the only viable option is to install Wordpress side by side with the appropriate plugin (for example as shown above Simple Link Directory PRO or a template like Chipmunk ), but this is not a good option if we want the community to create such collections. If only the administrator will be involved in the creation of collections and their curation, then this option is feasible. But an HTML file is also suitable for this.
For many communities, finding and saving external information is a very important and useful feature, and this can be done through regular forum threads, but the standard forum tools are not very efficient for this. If someone needs it, I can give more live examples of how it is implemented in Wordpress plugins and themes.
The ideal would be to get a plugin for Discourse that would convert the forum topic into a curated list where the list would be in the first post, the topicstarter would be appointed as its moderator, and participants could add links with their short description via the form (or composer). The rest could vote for individual items of this list, thereby raising the most popular items to the top.
