+### Syndication feeds
+You can "follow" almost anybody or any website that produces a syndication feed (RSS/Atom,etc.).
+If we can find an information stream and a name to attach to the contact, we'll try to connect with them.
+
+Notification
+---
+When somebody requests friendship you will receive a notification.
+You will usually need to approve this before the friendship is complete.
+
+Approval
+---
+Some networks allow people to send you messages without being friends and without your approval.
+Friendica does not allow this by default, as it would open a gateway for spam.
+
+Unilateral or bilateral friendships
+---
+When you receive a friendship notification from another Friendica member, you will have the option of allowing them as a "Follower" or as a "Friend".
+If they are a follower, they can see what you have to say, including private communications that you send to them, but not vice versa.
+As a friend, you can both communicate with each other.
+
+diaspora* uses a different terminology, and you are given the option of allowing them to "share with you", or being full friends.
+
+Ignoring, blocking and deleting contacts
+---
+Once you have become friends, if you find the person constantly sends you spam or worthless information, you can "Ignore" them - without breaking off the friendship or even alerting them to the fact that you aren't interested in anything they are saying.
+In many ways they are like a "follower" - but they don't know this.
+They think they are a friend.
+
+You can also "block" a person.
+This completely blocks communications with that person.
+They may still be able to see your public posts, as can anybody in the world, but they cannot communicate with you directly.
+
+You can also delete a friend no matter what the friendship status - which completely removes everything relating to that person from your website.
