Anyone in the Harvard community can apply for any of the services offered by HCS. In order to get a mailing list, you only need a valid harvard.edu (or hbs.edu) e-mail address. You can make a list instantly at our list page. If you would like a full account with web a website and a real e-mail address, you should fill out the form here. Again, anyone in the Harvard community can apply for an account as long as it has a specific purpose and benefits a group of people.
If you would like a personal account for any reason, you can get one by joining HCS as a prospective member. We give accounts to prospective members after they've attended and participated in two regularly scheduled HCS meetings.
