Thanks for the kind words, and no need to apologise for the wall of text - it means a lot to know that people are so passionate about the situation!
I agree that SubscribeStar would be the preferable option, and I altered the tier goals on my site to reflect the new situation. If enough people migrate then I can go back to business as usual - with more creative freedom! - but if not then I'll be forced to very seriously consider extremes like Steam and the resulting necessary graphical change (which I don't want to do, but Steam won't allow modded KK assets).
