Sorry I am fairly new to using WordPress but I am seeing some weird things. My site shouldn't have gotten any visitors besides one or two from Pinterest but I see people accesing parts of my website I had no idea existed. For example, they accessed http://www.mysite.com/feed or /robot.txt or the /feed comes up with an XML file of my site: "This XML file does not appear to have any style information associated with it. The document tree is shown below." also the /robot.txt comes up with "User-agent: * Disallow: /wp-admin/Disallow: /wp-includes/"Sorry I don't understand what these mean. Can someone be kind enough to explain these.
