I just read through some of John Fotheringham's Master Japanese ebook, of which the sixth edition was just released, and it's got some a lot of good advice in there, well-packaged. If you want some inspiration for your Japanese learning, it'll be worth a buy:

(Not that I'm learning Japanese, but I read the general language-learning parts, which is about 1/3 of it.)

I only read through the blurb but was intrigued by the "up to 30% off Skritter" offer. How does that work?

Thanks for that. I bought it since it looked very interesting and it surely is. Fun and captivating. Most of the tips do work equally well on Chinese as well. Note, if you like to buy it, sign up for his free newsletter and you do get a promo code worth 25% for the e-book.

@阿福 In the book it says that you can buy a 6 month subscription for 9.99 a month with a promo code. I think however that that is what it cost already for a 6 month subscription (59,99 US$) if you do it from the app.

Citation from the e-bbok:

The coupon code XXXXXXXXX gives you a
monthly membership of $9.99, instead of $14.99
for the first six months. Note that this discount
can only be used when signing up via the website
(not from within the app), and is valid through
January 1, 2014.

It's a promotional offer for new accounts, essentially giving new users a taste of the monthly rate that old users are grandfathered into. Won't apply to the existing accounts.

Thanks both. Now I'll have to read and make up my mind (and that's hard). Drat.
