Dear Ms. NOTA,
It took me a short while the other day to figure out what "NOTA" referred to. This made me feel slightly smart. Also, to your question, I've lurked a few times on this site over the past few years, and made a handful of posts on another account. I might recognize a few accounts if I saw them; otherwise I would say I'm new. "Mostly new." Thank you for your question.
As for the next poster, I went to the "Stupid Zone," closed my eyes, scrolled a little and fingered where I knew the names would be. My finger landed right in between posts by NOTA, and a seemingly new person named "Taru." My conclusion is that there will be half a post by each.
