This whole situtation is terrible, and I really hope it gets resolved soon and in a way that supports creators. I'll be subscribing shortly, and will try to keep doing so as long as it's feasible for me. Especially as someone in a vaguely similar situation, and someone who loves your work.
But I am curious as to how the "pre order" thing will work out. How're you planning on fulfilling that, especially for those who're only able to stay subscribed for a short amount of time. I apologise if I come across rudely or insensitive (which is definitly not my intention I am legitimately just curious on how you'll go about doing so, especially with the concern for which storefronts could be used in future).
