I can see from posts like this <Post #: 68429439> that @600mL is aware of the Reply button, but either sometimes forgets or experiences a glitch in HC where you start out replying to someone (with the "original posted by ..." visible in the yellow box above), but when you click the <<post>> button, the reply mode reverts to a new post.
I think this is more common than people realise, and HC should fix it. One way you can lose the reply mode is by using the Backspace button near the top line of your response, but I think there are other glitches.
