Cobra Guardian, if that's what you're referring to, is still up at Webscriptions and slated for the Jan 2011 bundle.
But apparently their author/series/bundle listings disappear if you have flash turned off in your browser, which now explains why I always had to open a different one to browse the Webscription site. I always thought it was some weird javascript issue since I'm using one of those smaller niche browsers on my laptop.
