Off day today in Mylot?

You can only read this post but you can't respond to it. I have been trying to reach out to many discussions since this morning but it is not possible. I thought my friend's post is destined to be deleted as there is no provision for responding not until I move to another discussion and the same thing happen. Is this another glitch in mylot system? The other day I responded to someone's discussion and it left a big gap in the page which took me by surprise as well as other mylotters who came in to respond. It seems today is going to be a bit quiet in mylot for new discussions as we can only view the discussion but could not respond.
