Hey Asher!
Yes, it's in this one - fourth chart down:

"...we can see a huge number of accounts (11.5k) returned to posting in December after being inactive in November."
It's a pretty large number in relation to the total number of active posters. There's some nice anecdotes in the comments as well from people who have come back to posting.
Great! Thanks, i thought I'd seen something. That is a large number of brains returning prove their worth isn't it :)
