Its, yay or nay
And
It's, yay or nay
Both grammatically correct too, although the first example can be considered to have no context for the reader to understand what *it* is. (You forgot to use a comma and a question mark inside your quotation marks'.)
I even missed the coma in the forum thread title too, having instead used a full-stop.
I'm not quoting you either, hence the lack of quotation marks, although both examples could be considered correct, depending on the context.
I imagine this is also riddled with errors too, but as I'm not five-years-old', I think I'll get over it.
