id editor walkthrough, without registering

Is it possible to go through the Id editor walkthrough without registering for OpenStreetMap? IS it available at another web address?

I know this might seem a strange request. I'm going to be teaching a class and will say "Follow this tutorial, then I will continue with the next instructions" (I will then have them login & I will demo the HOT tasking manager). While some are waiting for others, I don't want them to start editing. This group particularly, I expect to need to make it clear "now we're going to edit real stuff".
