The only command that sends a message to the staff is the wish command. You shouldn't use think or feel for communicating with the staff, please.
As Ashyom mentioned, staffers monitoring you can see your thinks and feels, but they should not be treated as forms of staff communication. Not all staffers are monitoring all players all the time. Even a particular staffer who has sent you a message directly may not be monitoring your thinks and feels or be in the same room with you (which means we may not see OOCs either).
So, unless that staffer specifically suggests otherwise, please stick with the wish command. Think and feel are IC commands, not OOC ones.

PS-- I realize this probably isn't exactly what you meant, Ritley, but it is worth mentioning. A lot of confusion ensues when we're communicating with a player who doesn't seem to be responding, or when we only get chunks of the conversation.
