This was an experimental class, and we are debating about setting up a Sage server. I have a local installation of Sage for my own research, but was interested in the possibility of using it for this and other classes. We're also a fairly small school (1400 total students, with about 6-12 math majors a year) so it's not something we wanted to allocate a lot of resources to before doing a trial run in at least one class.
I do see your point though, and if this works out, it'll be worth the resources to set up and maintain our own server. Thanks Jason, for fixing the other problem and looking into the username stuff. ~Gwyn On Feb 7, 1:03 pm, John Cremona <john.crem...@gmail.com> wrote: > Is there any kind of policy stated anywhere about using the public > servers such as sagenb.org for class teaching?
