User Creation and Registration

Is it possible to foreseen to create a user with no cloud space available? I mean an user that can access only to shared folders but without a personal space? I’m opening public information to customers and I don’t want them to put their files on my server up to now I limited to 1 GB but I prefer not to give them space…

And the user registration service is not working! Now I have to say to people to write me if they want the access….

You can create users manually, you can use scripts, for example with a python library: https://github.com/owncloud/pyocclient, there are some registration apps (and perhaps others) that might have such a function or you could create one.
