I have a mac and a new pc. The Kindle publishing software only works with the pc. I have five manuscripts waiting to be formatted and uploaded into Kindle. I completed the uploading of one a few minutes ago. Kindle says it will take 12 to 48 hours before it'll appear on Kindle. This is so exciting. I've been too excited to sleep lately. Got to get back to work to upload the rest of the manuscripts.... what a year it has been, full of new and strange things. I hope I'll be able to share what happened to me lately. It's too painful to share right now.
