If ever I take it upon myself to publish an ebook, I shall very seriously research all area's of this site and any other site that can provide me an inkling of knowledge needed to accomplish said task. For the time being, I am simply trying to convert my technical books to electronic format for my Toshiba Thrive tablet. The learning process is not difficult, but it is complex in knowing what I can or cannot do because certain new technologies are not yet implemented in Sigil or Aldiko or Calibre. Standardization is what is ultimately going to bring me to a point where I would feel the ability to create a work of my own would be worthwhile. But with your gracious help and forbearance, I am happy to be a lurking member, for now.
