Over at Deafness and Hearing Aids, the author is planning a "Little Book of Hearing Aid Tips" full of advice and information for someone who is getting hearing aids for the first time.
This book would be free and would be in the form of an ebook and a printed version. If you want to contribute, email the Deafness and Hearing Aids author from the contact page on the website. According to the post, "[j]ust one paragraph is enough, even one sentence if that's all you need." So go ahead and share your wisdom.
