(GOODFRIEND) - Make a friend into a goodfriend.
Goodfriend allows you to make one of the users on your friendslist into a good friend.
A goodfriend appears higher on the userlist. To make a friend into a goodfriend, use the command "/FIDHERE". This command must be capitalized!
You also have an option to add a sound to a goodfriend. Sounds are heard when a goodfriend enters the chat, or whenever they send a message.
To enable sound for a goodfriend, use the command "/SIDHERE". This command must also be capitalized!
Goodfriends will appear higher on the userlist as well as your friendslist than your regular friends. They will not appear higher than users who are a higher rank than them.
