Hi LizBit! Thx so much for reading! I’ve asked myself the same question. I don’t believe so. But as the saying goes, get two birds with one stone (sorry, a bit violent). I draft on KoalaQuill then paste it on to Medium. I don’t publish unless I’m really confident which is nearly never. But I might come back to it later, fix it, make improvements, then publish.
The result is I never worry about getting demoted on KoalaQ and I create drafts on Medium that might turn into a decent story.
