I have the same problem with the username zieglerk I recreated the account, but my worksheets did not show up again. Still, when looking at the list of published worksheets I recognize several of them, now filed as Owner: pub Last edited: *** days ago by zieglerk If there is any way, I can help to recover the worksheets -- actually the links between worksheets and accounts -- I would be happy to try.

Re: [sage-support] Re: sagenb.org server(s)
I appreciate the efforts that are under way to make sagenb.org more usable en masse. I'll patiently wait for the improvements to take effect. In my ignorance, let me pose a related question. It seems to me the published notebooks are far different entities than those that are "active". Am I correct in this? Are they not essentially static content? Yet, I have no easier time browsing through the published ones, even though I need not be logged in to view them, than I have accessing and running my own. Could these two areas be decoupled? If it were easy to do, I think it would be worth it.

Not yet (though I suppose someone with root access might be able to move your login credentials with a lot of effort...), but you should be able to just download all Sage worksheets you care about at once, and then upload them at once. At least with the newest few versions of Sage, use "Download all Active". Of course, that will download ALL in the 'active' list! You should be able to upload this file in the dialog for uploading, even though it won't be a .sws file. - kcrisman -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

There are other people also working on this rewrite or other projects which restructure the notebook and make it more scalable.There is funding from an NSF grant to work on making the notebook more scalable, so it will get done (i.e., there's funding and committed developer time).

Here's a followup question, which might be considered a firefox question: At work I used firefox. The form filling for the log in page for sagenb.org has one of my ids VictorSMiller filled in.

Thanks William, I input demo.sagenb.org into my google search box and came to a website called Symmetric Group (Demo) Sage. However, how can I upload my worksheet, so that others can view it? Also, for a while, I thought the problem of logging in was me, so I created other accounts that you can delete. All of the accounts were created today within minutes of one another. The user names for the accounts that you can delete are 19eric, eric19., and eric19.

I just logged in and computed 2+3. However, I did get two indicators that it was slow today (I have a monitor script). Also, sage is getting some discussion on slashdot right now.
