Public servers where I can publish (share) a notebook?
I've spent some time preparing a notebook I planned to share with others, but it seems like publishing (or at least viewing published notebooks?) is disabled at sagenb.org. Is this a deprecated feature?
I thought it would be a great way to share a "living" version of a document that keen readers could then experiment further with. I guess I could just share my .sws file but that would mean extra steps of setting up a Sage account and uploading it before messing with it. But I suppose that is a workable alternative.
Just for clarification, sagenb.org is a special situation because it was getting significant amounts of spam with security issues. Hopefully someone else will give you some ideas; there are a number out there.
