Not really a big deal at all, but for the sake of getting everything perfect, when you reply to a conversation (at least when I do), the last post does not show the green online status light until you refresh the page. Any other prior ones were showing up fine...i.e. in a conversation in which I made 4 replies, the top 3 were showing the online indicator, but the last post was not.
This does NOT happen with posts. Only seems to be happening with the conversations.
