Congratulations Kovid and everybody that helped and thank you SOOOOO much. I use calibre a lot. It has such a simple interface, it is fast and the constant updates make it a wonderful and unique tool for conversion. And now that I also have a Kindle2 in addition to the Sony reader, the recent mobi conversion was a wonderful addition. And by the way, I have also put my money where my mouth is and have donated. Thank you, thank you, thank you!!!!!!
