Google Site Discoveries

I'm creating a web site for my final project and have discovered a few things others might find helpful ...

• There doesn't seem to be a way to rearrange the pages on the site map. If you accidentally forget to create a new page and mark that it should go below your home page, it becomes your first page and the only way to correct that is to delete the page and start over.
• Regarding collaborators and viewers: Viewers are just what it implies - they can look at the site, but that is it. Collaborators can edit pages, but they can't invite new people to the site or change the appearance -- they can simply update page content, add links/images, etc. Only the owner can determine who has access to the site and how it looks in terms of themes, colors, side bars items/gadgets, etc.
• Is a private site really private? Yes. Only people who are currently on your sharing list can access the site. Others get a message telling them they are restricted from viewing the site. I also tested removing a member to see if her access changed and it did. One minute she could get in, but once I removed her from the sharing list, she got the "access denied" message.
