You might have noticed that the Horde homepage received a new Demo button within the main navigation recently. We did indeed manage to get a demo machine up and running at demo.horde.org. The installation got updated to the latest releases just yesterday and Ansel - the Horde photo management application - got added into the mix. Feel free to test drive this new application as well as the other components on demo.horde.org.
If you experience any problems please let us know.
In principle you shouldn't be able to break anything on the installation. It is a virtual EC2 machine and we will update the image every once in a while when there are new releases available. Any data you store on the machine will be resetted at that point.
You should also be able to mail to the two demo users email@example.com and firstname.lastname@example.org. Mailing to the outside is not possible - for obvious reasons.
