@peabrainer It's not a permanent change, it's just because they have so much content at the moment (whereas surges are just to quickly clear a small backlog). I like the slots for getting me to commit to an hour but I also prefer surges for flexibility and better earning potential.
@Baby89 well done! You'll have missed the cutoff for the December round, but later in the month you should get an email asking you to complete the availability survey for the January round.
