you have two possibilities:
1. You set up your own environment, consisting of the collaboration
server Collaborilla and a WebDAV server.
or
2. You use our server for publishing and collaborating.
If you choose 2: send a private email to me, I will then create an
account for you (it's free) and send an email with details on how to
configure your Conzilla installation.
