Here's my situation. I'm starting to develop a Zope-based site that could have 100,000 or more (a lot more!) self-registered users and maybe 20 to 30 content creators for about 15 different content areas with only a few content creators per area. 1. I think the large number of users should be no problem for one of the DB-type user folders (GUF, UserDB, MySQLUF, ... yet to be determined) 2. I think the number of content creators and areas is within reason for using local roles. They won't change often. 3. I can't imagine what will happen when I want to add a local role and Zope tries to build a SELECT list of 100,000 names and sends it to my browser! So am I crazy to use Zope for something this size, or just too dense to see the obvious solution? Regards, -Dennis -- Dennis Nichols nichols@tradingconnections.com
