Including shared files in existing collections?

There are quite many podcast collections in several languages, and what if I find content that hasn’t yet been shared - can I upload it to one of those? Is that possible? Hopefully I’m not the only one enjoying the lessons. In a few cases there is still much more to study, so instead of waiting for the provider (not always obvious) to upload the rest of the pods/parts/chapters, I could at least upload a few of them.

Unfortunately, you can’t add to somebody else’s collection. This is something that we should have eventually since it makes sense in the situation you describe. I have been in the same situation myself but have had to create a new Collection of my own to add more parts. What you can do is let the content owner know by writing in the Lesson Forum. Hopefully, the owner should see this and you won’t put up duplicate content in different collections.
