Oh man amethyst keeps posting my notes before I finish them. Anyway I was mistaken about this. I paid a donation and it showed in my history as a bunch of small payments.

Latest amethyst has a draft function. Sometimes when you post and quickly look it may be showing the incomplete draft but it will quickly update to the final posted version.
Also, when you zap a post in amethyst that has multiple recipients (like an amethyst release note) the split will be done by sending multiple small zaps.
