I believe so. Back in 2011 he said the next issue was to be the last. I believe he may have developed some health issues, but I'm not sure. I feel that last issue has already come and gone. He's a good guy and I was kinda concerned.
Using zabasearch, I found JJ's backdoor number and he answered. He has had some health issues and had no option but to "retire" and as of late has been better. He sends his "Hi" to everyone and will try to get on here in the near future.
