Help teach everyone.
This is a shared effort, and there's a place in it for you – whether you have five minutes or five hours, money to spare or just a skill to share. Here are the ways people help keep the lessons free, clear, and growing.
Suggest a lesson
tell us what you wish someone had explained plainly.
Volunteer to write or review
share what you know, or help check a draft for accuracy and clarity.
Translate a lesson
help more people learn in their own language.
Partner with us
libraries, schools, clinics, and groups that reach learners we can't reach alone.
Support the costs
a small voluntary donation keeps the site running and free for everyone.
Reach out
Tell us how you'd like to help.
Five minutes or five hours, a skill or a suggestion – it all helps. A real person reads every message.
