Exactly what I was going to say :)

Wow, not sure how this happened, I would think that the system would block a new thread from being posted when the subject is empty and/or there is no content.  Let me investigate.  In the meantime, @M_313, what happened from your point of view?

Hi, 

My email notification says that someone replied to my forum post "Help on Noise Correlation matrix" but instead I was redirected to this. I have no clue how this extra thread got created!!

Shall I go ahead and delete this post?

I am still investigating how this glitch happened as there are provisions in the code to prevent an empty thread to get posted, so obviously, a bug somewhere...  I was hoping to get a clue from you in order to reproduce the issue but you say you have no idea how this happened and I believe you.  I will delete the thread myself, thanks.

Good one!
