I see 3 times the same.

Hello, when i want to send a intern mail, i see 3 times the same.
I mean, 3 times i cancheck the same thing.

Look at the pic, wwhat i mean.
What must i do to delete 2 things. Or maybe it's not good translated. 

Thank you. 

it's not the same thing.

you have 3 options that gives you the option to send 2 cc emails and 1 notify email.

1 => a copy of site msg to personal email of member

2 => a copy to your own email address

3 => a notify email to member by email (saying that there is a msg from you)

Unless he's sending the message to himself! 

 True :-)

Perhaps we need to explain what each of those three things do.

 The caption says what each one does - my 7 yr old looked at it and knew what it meant.
