and not simply a name changer or even simply a poster who you haven't seen around before (it is a very big site after all...)
I have seen people say things like "the OP is a new poster" or "interesting first post" and similar, usually when they're doubting whether the poster in question is being serious.
But how can you actually tell whether someone is new or not? From what I can see they're only basing it on the fact that they don't recognise them but like I said they could be a name changer or even simply someone they haven't come across before.
Unless there's another way you can tell whether someone is a new poster that I've missed...in which case please let me in on the secret!
And yes I have recently name changed myself....
