Yes, it’s possible in the Discourse architecture, but the powers that be decided to make two separate instances (presumptively at twice the cost or more).
In other words, as far as what’s technically possible:
- A seaparate top-level category can exist for Ask/Support and a URL can redirect people directly into that category to look at various sub-categories of support questions (and answer).
- The support categories (and subcategories) can have their own CSS for a unique coloring and look/feel, if desired. It can also have its own “banner” content at the top introducing people to how the support system works.
- Plugins for accepted answer and topic voting can be enabled category-by-category, if desired.
- The support content can be hidden from the main top-level listings of new content etc., to keep it separated and only viewable when someone lands on the support category page.
But anyway, all of the above is purely hypothetical on what’s possible with Discourse, and not what’s actually going to ever happen.
