We noticed his message.  We didn't delete any data, so getting the site
back is certainly possible.   We waited a few weeks but boxen had to be
shut down for security reasons.

I backed up the data (both the mysql database and the Drupal files) before I sent that message, so it should be ready to roll out again. If boxen is back up again, I can try to do it in the next week or so. Or if someone else wants to do it, please let me know.

I think having public cloud files, like William just enabled, plus a curated index of really nice examples, plus maybe a wiki page of short simple examples, is a better approach than the rather heavy-weight interact.sagemath.org. I think the biggest thing I took from running interact.sagemath.org is that we should do all we can to lower the barrier between creation and sharing. I now think that the barrier of posting to a separate interact.sagemath.org website (and actively maintaining it against spam) is rather high compared to just hitting a button to publish a worksheet.

Thanks,

Jason
