This is not a complete list, just whatever I can think of for now....
- You should have gotten an MIT ID number in an email at some point during the summer.
- Setup MIT Kerberos username and password: this is going to be your email account and Athena (MIT's computer lab system) account. For instance, my Kerberos username is "lululi," which means that my email is lululi@mit.edu and that I use the username lululi to log into Athena cluster (both on a physical machine and remotely). You only get to choose your username once, and MIT does not allow aliasing names the last time I look up, so I'd recommend choose something sane.
- Setup MIT email forwarding (optional): https://ist-mit-edu.ezproxyberklee.flo.org/email/forward What happens is MIT uses Outlook Web which is something any sane human being would not want to deal with (plus it has a super small storage limit), so I'd recommend forward your mit emails into something else (a popular choice is gmail). It takes less than a minute to setup.
