The Settings menu link in the Control Panel offers a variety of options for customizing your site, including changing the privacy of your site and your Google Analytics ID.

Privacy

By making your site private you can prevent anonymous viewers who don't have an OpenScholar account from seeing your content. Additionally you can control whether your posts will be shown in other user's news feeds.

By checking the Anonymous Contact checkbox you are allowing all site visitors to contact you via the site contact form. Leaving it unchecked will restrict the contact form to only registered users who are logged in.

Google Analytics

Make your site work with Google Analytics, by entering your Google Analytics account ID. The analytics data is automatically transferred to Google Analytics for all content pages on your site.
You must have Google Analytics account.
