I had been using the Alloy Demo for Educational purposes for the past year, but looks like that's been shut down. It was handy because i could compare our install with what Episerver had. It would reset once a day to remove any changes.
The main Alloy Demo itself seems to still be running. However logging in can't happen without registering. The Demo page has this on the corner of http://world.episerver.com/download/Demo-Sites/Alloy/"Register as member of EPiServer World and you will get all logins you need to use our demo sites."
I did'nt get anything. So how do we get in???
Maybe it's personalized content but the right column on the URL you supply for me has:
http://alloy.episerverdemo.com/ Role: EditorUsername: epiuserPassword: episerver
Tested and it works. If you're a a partner you can also see admin mode details.
