How can I get a FREE premium qualification?
I use todoist.com just few days, and I find I have no rights to use some functions (like 备注，成果效应, etcs).
If I have a premium account, or may some limited days, I can feel more acknowledge with todoist, and it will more helpful for me to judge whether I need to buy a premium qualification.
