A few days ago I posted this:
A few months ago I offered to give a book to each new person who subscribed to my blog up to 500 – I have 200 hardcover books left (now about 50). So, the next 200 new subscribers will get a free hardcover book.
I then added:
Just subscribe here and email me your address at firstname.lastname@example.org.
I think I should have been clearer – make sure you send me your MAILING ADDRESS so I can mail the book. Sorry for the confusion. I have not figured out how to email a hardcover book.
