You mention that you did not want a cdrom included with your book. For those of us with slow net access (33.6 modem) I'd go buy your book to save me the 100MB download for Oracle8i. (Assuming Oracle would let you include it with a cdrom). Also, I have found Oracle's web-site to be one of the hardest to navigate. It took me about an hour to find where to download Oracle8i for Linux, maybe they ought to read your book. Now the praise: your book, webSite and ideas are all very good. Keep up the good work. I'll be spending the next few weeks devouring the content of your pages. Thanks
