To further the information on this.

The mod commands mute, unmute, kick, and warn all use a MemberTransformer to collect the member to take action on. The ban command is the only command to take a User. This allows the banning of members not currently within the server.

The commands mute, unmute, and kick all require a member object to proceed with the action.

---

Therefore warn should be changed to not require a member object. For the remaining commands requiring a member object, stronger error information should be provided.

This has now been implemented into master. Error handling will share if the member cannot be resolved in argument transformation.
