I must make one important correction to what you said in your introduction - I'm Belgian, not German.
After you have done the corrections, could you print out the document please?
I've noticed several more corrections I'd like to make to the book, if it's not too late.
I have one correction for the newsletter - our phone number has changed.
Make sure you do all those spelling corrections carefully before you send off the letter.
