Thanks for bumping this, Richard, I had missed it.
I had also paid for a new 2-year subscription and was really angry at what they did (at first). I had suspected for a while that there was something wrong. When Sept 11 happened, Sue was still a still a semi- regular contributor to the forum, but things went south after she stopped moderating and there were tons of trolls & people posting under aliases.
I know it is very hard to publish a niche magazine, and they often don't make it. I also got stiffed by Helen Nash's mag (Pond & Garden) that went under right after I renewed that subscription.
I think both of those magazines failed because the hobby of "ponding" was at it's height of 'craze', and then plummeted in popularity. There are many issues that, for some people, make it difficult to stick with- predators, maintenance (labor), water quality issues, price, leaks, high-maintenance fish, safety, differing opinions, winter, etc.
I've been to a couple of talks by Greg S. at the Chicago Botanic Garden, and I thought they were informative.
Even with that I still think they owed their customers some kind of explanation/apology, if not a partial refund.
