Anna sounds amazing! Obviously you are free to pick and choose among the suggestions I have made. I took the liberty of making deeper edits since this letter has a more formal purpose than most notebook entries. Well done!

One further suggestion: If you know the name or title of the person you are addressing this letter to, it would be better to use that in the salutation instead of 'To Whom...'

Please let me know if you have any other questions for me :)
