[Zope] newbie questions ?

Hi, I spent my week-end learning how to use Zope, it was a nice painful experience. Nice thanks to Zope itself, painful because of the poor docs. The How-Tos helped me a lot but it is a real mess. Here are two questions I did not find the answers : - how to ask for authentification to see my web pages (not manage, just see) ? In Apache one has to put a .htaccess file in the directory. - how to limit the size a folder ? I want to give login to friends so they can add photos in a folder but I don't want to receive more than 200MB of data in this folder. Thanks, Olivier.
