Deviantart does not have an automatic "mutual friend" function.
In order to become a "mutual friend" you need to watch that person, and that person then needs to watch you back
Some people told me they wanted to make more mutual friends, so I made this journal for them. If you post in this journal, I will post your icon here, that way people can watch you and you can watch them back to become mutual friends
If you add these people, they will add you back and become mutual friends:
(da says mutual friends get special privileges but I have no idea what are those lol)
