How do streaks and leagues work?

Your streak grows each day you do the warm-up, post a work or a daily sketch. Once a week you get a spare day that covers a missed one (you can hold up to two, and buy more for 30 bonuses). In the league (→ League) you spend a week competing in a group of up to 30 people on your tier (Bronze to Diamond): your score is the experience you earn that week, the top 5 move up, the bottom 5 move down (in groups of 10 or more), and places 1–3 get 20/10/10 bonuses; results come on Monday.
