@DevTantia – I think of the first post as “Original Post” (“OP”) or “Topic Starter”. There is only one of this type of post per Topic, and it always stays at the top of the Topic page. Only this special “OP” post contains the extra fields in the Composer (as you can see just below) like the Title, the Category, and the Tags - none of the other posts within (below) the OP provide these extra fields.
The OP is also the only post to display the Topic Map (always at the bottom of the OP) which shows helpful statistics regarding the community members’ actions and engagements with that particular Topic, like so…
I think of the rest of the posts as “Reply Posts” or “Topic Replies”. (As you can see below here this Reply Post Composer is without the extra fields.)
