A Private Omeka Website?

I am building an Omeka website for use by my students. Is there a privacy setting for the site as a whole so that anyone entering the site URL would be taken only to the Login or Register screens. I am aware that each item can be private. I would also like that the skeleton of the site, complete with menu tabs, not be visible prior to login. Please advise.

The only privacy settings are those built in for items, collections, etc. What you are describing would require a plugin and/or theme work.

OK, for now I will have to live with what's there. Maybe next year I'll be ready for your workshop. Thanks.
