The Friends and Foes System
How do I add users to my friends / foes list (or remove them)?
Search for the user. Click . Add the user as your friend or foe.
You'll find those symbols on users' comments as well, and elsewhere on the site. Basically, anywhere you see the following symbol you can decide to add a user as friend or foe.
To remove a friend or foe, click on their friend/foe symbol and change them back to Neutral.
Where can I see my friends / foes?
Can I see other people's friends and foes?
Sure. It's similar to checking your own friends or foes list (http://slashdot.org/my/friends); simply replace /my/friends with /~username/friends. Follow the same pattern for checking other users' foes list.
What are fans / freaks?
When you select someone as a friend, it makes you that user's fan. To see people who have chosen you as a friend (your fans): http://slashdot.org/my/fans. To see other users' fans, replace /my/fans with /~username/fans.
"Freaks" are people who name you as a foe: http://slashdot.org/my/freaks.
What are comment modifiers, and how do they work?
Comment modifiers (see http://slashdot.org/my/comments) let you filter comments in a story. There are many comment modifier options. For instance, you can attach a comment modifier to a friend, foe, fan, freak, friend of friend, or foe of friend.
The reason this is cool: let's say you want to be able to read all your friends comments, but many of their comments lie at the threshold of 1, and you read at a threshold of 2. If you go to your comment preferences, you can make all of your friends' comments appear at a score of 5.
