The wordpress.org support forum is a high-traffic, high-volume forum, with probably hundreds of new posts a day.
It’s got three particularly interesting categories:
- Plugins & Hacks - Embedded example
- Themes & Templates - Embedded example
- Reviews - Embedded example-1, example-2
These are special because they’re not primarily accessed via the forum/category index. Instead, they’re accessed via distributed embeds, sectioned off by tags.
In other words, no one’s gonna be writing their support request for Co Authors Plus in the Plugins & Hacks forum. They’ll do it via the plugin’s dedicated support forum, which automatically adds the ‘co-authors-plus’ tag needed for a post to show up in that embedded forum. (This also adds the handy benefit of being able to cross-post between two plugins in the occasional case when a post relates to both.)
It works the same way for themes. I’m not quite sure how it works for reviews but the post-flow is the same.
Another similar example is Vanilla Forum plugins.
Hypothetically speaking, say you were asked to convert the entire WP Support forum to Discourse. How would you do it?
