Password for each workgroup

[Christian]

At the moment, when I write this lines, two workgroups have and use already a special password for their work here. For the other ones, Passwords are already prepared. At the moment you will use it, because you don't want to make your work complete in public, tell me, please. I will activate the password immediately.
If you are a member of such a workgroup and want to have access and don't know the password, write me an email, please.
