We have three different membership types, as can be seen in the table below. Student memberships are available to all students currently enrolled at a university. Young professional memberships are available to all people who graduated from their most recent degree within the last 3 years. Regular memberships are available for all other people.

All these membership fees cover membership for at least 1 year and up to 2 years. Those signing up for membership before 1 October 2024 will be members until 31 December 2025.

In order to make our membership accessible to people from a wide variety of countries and income levels, we have applied a pricing system that varies depending on the country of residence of the member. We use the World Bank's Atlas method to classify countries.
