Hearing that Korea now has a badminton magazine, have you seen this magazine?
In addition, Badminton-Asia Magazine folded?

Yes...it folded last year. The last issue I had was from January 2007, with Gade on the cover.

now? When hasn't Korea had a badminton magazine? Wolgan Badminton (http://www.ebadminton.co.kr) has been going steadily since 2001. Before that, there was some sort of hiatus but the magazine had existed back in the 80s as well and I believe that a different magazine filled the void in the 90s.
