You didn't post it in there, someone has either reported the thread and had it merged, or an Educator has merged it for another reason.
But it shouldn't be in there, it's completely different, and a very good read. It deserves its own thread, just like every months blog that you post.
@simone_w , can you shed any light on this please?
Edit; And by merging it, it now shows on my profile that i visited and posted in that thread. Not happy about that.
