Than you for your patience, and Fantastic! I am new to discourse and managing forums, the wording for [Discourse API Docs](http://docs.discourse.org/#tag/Topics%2Fpaths%2F~1posts%2Fpost) topic\_id could be clearer. ‘Required when replying to topic or post.’ or similar.

In regard to group\_id? How is this discoverable? In the GUI, I see the title, short\_name (name) and nothing else. From the api docs, it looks like I need to GET from /admin/groups.json, but that returns no value.
