If you are new to Socialism and the manifesto contains a lot of unkown historical references, we encourage you to visit the explainer page.
The membership is $40 to handle the fixed cost of the material + the membership to Socialists International.
The membership is progressive scale based on one month of income. It's the average income after taxes minus the monthly rent (the mortgage is not deducted because it's building personal capital whereas a rent is not.)
Membership is based on a comrade income (of course, there is no verification, it's the honor system.)
In order to join you must download the membership form and you must agree to the principles of the Socialist Manifesto.
The membership must be paid to the Secretary of your local branch using a paper form. A comrade cannot join using the Internet. The goal is preserve privacy but also force the comrade comes back at least twice for voting rights.
