I only checked the old ID thread to see if a member that IDed it gave some descriptive plant features for the ID or any additional info for the plant and was actually puzzled that there wasn't a reply post given, the reason for my confused icon. I was curious who IDed it back then, that's all, as it couldn't have been these 2 "guys" here in this thread, they don't go back that far.
Maybe you got the ID privately or in another thread, perhaps in the succulent forum or something.
The ID thread shows no replies as you can see next to the number of views.
(Members can't delete their posts, just the contents within the post but it would still count and show as a reply and still be in the thread.)
