I totally agree. Actually I just thought about the checkboxes too, independently from this thread
It would just be very handy to, for instance, gain new members for your guild. If you mesage someone you would like to recruit, he cannot see your guild rank until he's actually joined.
And another thing:
"send to ... one of your contacts". It's useful in some cases, but often I want to send 1 letter to several people I know (for instance to friends across a continent), and I end up copy-pasting the letter several times. Is this intentional? Because it kind of breaks the atmosphere.
Why not add 'send to some of your contacts'?
