As people have expressed interest in possibly using the Google Sites medium for our D&D campaign online warehouse, I've been sending out invite emails to allow access to the system.  As a collaborator, you should have access to edit any current page, create new pages, and add posts, documents, and other content.  You can't delete current pages, change over-arching site settings, or administer users.  If you need something done in that realm, let me know and I'll help out.

If you have questions about how the system works, feel free to post here or email me directly.  I'm still figuring things out myself, but have floundered my way around quite a bit of the system.
