Here is the page where SSME members can come every year to pay their annual dues electronically. You only start paying dues after becoming a member. You can find information about membership here:
To keep your membership in good standing, you must pay your dues every calendar year. You should plan on paying dues on January 1. But, if you have just joined the society, you should pay your dues immediately unless it is September or later.
The price of your membership dues is variable and is based on employment status and salary. Click the button below to see all the options, and then pay for the one that fits you. You must pay using PayPal, but you can do this even if you don’t have an account.
