That's terrible news to hear.
I didn't know the guy at all, but I have read quite a few issues of Negative Guest List, as well as Dirty Alleys Dirty Minds. It was good stuff. There are some real heartfelt tributes here from Mess and Noise.
In Australia I think the "zine community" has grown a lot, though not so many punk rock zines can be included in that growth. Particularly ones with as regular production.
Sad news to hear though. RIP and best wishes to his friends and family.
