|Thanks. Good to hear that there is still activity on the API development as time permits. For now I decided to "mock" an API call to return a list of available forums (which will return a static ItemSummary list for now). When you get around to implementing something it should not be to difficult to replace that mock.
As for the forums at the end of an article a pointer to that should ultimately be returned through the GET V1/Articles call. That would probably mean an extra field in the ItemSummary but that way they are accesible as well.
