I haven’t done that, but one thing to consider is how posts are structured in the KB section.
Your latests posts in the KB automatically go to the bottom of the list. And you’ll have to drag/drop them to reorder them.
So if you want the latest posts to be at the top, it might not be your best solution. It’ll be okay at first, but as your list of posts gets longer, it will become a pain.
I discovered this with a previous community that was using our KB for publishing content. After a few weeks, we identified the pain point above and switched to using the Product Updates module. Product Updates works more like a blog feed with filters and the latest posts are always at the top. So that might be another solution to explore.
(Note: If you choose to use the Products Updates module, know that the filters are tied to “Product Areas”which are the same Product Areas used for the Ideas module. So while you can adjust your use case to that module, setting up the filters (Product Areas) will also impact the Product Areas available to be selected for Ideas.
