What a wonderful way to get a little feedback and share the excitement of the milestone!
By far, I spend the most time bouncing between the Amazon Kindle group and the Calibre group in the forum. I've learned so much as I've dived into the world of mobile reading. I can't think of any improvements. I love that the forum is searchable and I've found many of my questions answered by simply doing a search.
Thank you to the moderators and the MobileRead team!
