Below are commands which @grouper will respond to with details explaining what they do. The commands will only accept a single group to modify, however for the 'user' argument there are several varitions.
The user parameter can accept a list of users when using common separators (+ & , and). For example:
"@grouper add @user1, @user2 and @user3 to <group>"
In addition, it can also accept mutiple types such as a existing user or group. There is also a alias called 'me' for referencing yourself instead of using your handle.
e.g. "@grouper help"
e.g. "@grouper add <user> to <group>"
e.g. "@grouper remove <user> from <group>"
e.g. "@grouper swap <user> into <group>"
e.g. "@grouper list"
