To log into OpenScholar, click on the Login button at the bottom of your OpenScholar site and enter your netID and Password. Depending on the setting you chose when you created your site, your site could be Public, Private, or anyone can see it if they have the link (basically public but not indexed by Google).
When logging in to a Lab site on OpenScholar for the first time, your site will be set to Private. We do this so if you would like to build your site out first before presenting it and making it public to the world, you can.
If you would like to make the site public, simply log into your site (by entering your netID and Password), go to the Admin bar > Settings > Global Settings > Site Visibility. Change the radio button from Invite only during site creation, to Public on the web.
