PM doesn’t work in the beta forum? Hmm, never really tried it.
Will update credits, will investigate PM’s.
It may take an iteration on the Kindle version. Turns out their presale window was 10 days not 7, so I had to put in a “final” version to get October 1. However, since on a normal Kindle book that’s on sale I can update content and have it through in about 12 hours; not sure what that means….will see once the presale goes live. In theory, I should be able to update content on the normal time scale, all of which is before any is released. However, pre-orders are a new thing for me.
