Are test161 submissions open to the general public?

A friend of mine was attempting to work on ops-class this summer. And he was wondering if he could use the test161 server to test his code. Currently there’s no way to create an account on test161. Or is there an alternative way? Thanks

You can run test161 locally - there is no difference (other than overlaying some files, and “securing” the output) between your local test161 and the server’s test161.
