Ok, thank you for that, the subspace thing is good to know. How I would set this up is now starting to puzzle me. So let's say I have 3 departments Engineering Hardware Software All three will collaborate on the same projects and may need access to the same wiki content, but all may also want private pages that are department specific. So I guess if I didn't a separate wiki department, they could use interwiki links to reference project pages. This would probably necessitate some people from each department being in the other departments wiki group. But then if they created a private namespace, the people from the other department could see it. I could combat this by creating two wikigroups for each department, like wiki_engineering_public, and wiki_engineering_private. Then only departmental members would be in the private group and namespaces could be in the private group to protect. Or I guess everything is public, and then group perms on the namespace to protect? The problem is that we're a pretty small company 250 people and most of the people are cross department/project functional. I'll look more at the perms side of things. Thank you.
