These questions are related to private sites.
It means that only selected Wikidot.com users (of your choice) are able to see it and browse it. You can choose the site to be private either when creating the site or later in your Site Manager » Public or Private settings.
There are 2 classes of users that have "view permission":
"extra access" users will be able to view all the content from your site but will act as "Wikidot.com users" when it comes to site modifying permissions (SiteManager » Permissions).
In other words — people that are not your site members and you did not give them "extra access" will not be able to browse your site but instead will see the default landing page.
For whatever you want provided you comply with our Terms. People use it for personal notepads or workspaces, teachers use it for their classes, some people use it for online collaboration…

All the RSS feeds from private sites are password-protected and only members of the given site are allowed to access them. The authentication mechanism is HTTP Basic Authentication — supported by most of the feed readers.
However due to security reasons the password for accessing the feed is not the same as your log-in password. As a user name you should still put your email address but for the password please use the same password you are using for your private feed: please go to Settings in My Account and click on Notifications to find out the password.
