It's Halloween on SN, there's been a lot of spooky goings on happening round here...

Here we sit in SN's darkened saloon - fingers touching, concentrating on that saloon glass on the board.

Will we be lucky enough to watch it move in the half-light and, from the other side, spell out the missing word to make a sentence for us...

If you sense the glass has moved over a letter, you can tell the rest of us the letter or emoji (but only one of them) via a reply. If you think the answer is complete, just type 'goodbye'.

Multiple threads can happen at once - it's a big saloon, with many boards.

Got it?

Let's see if it works!

I'll start with the first question.
