Alas, as has already been said, the LiveCycle feature is proprietary and not free. So you won't be able to use it from ConTeXt. One alternative on Windows maybe Foxit PDF Reader which is available for free, and can do some of what you want with low-cost add-ons. http://www.foxitsoftware.com/pdf/rd_intro.php The 'pro-pack' allows annotation: http://www.foxitsoftware.com/pdf/reader_2/addons.htm#advanced And there is also a Foxit PDF editor as well, but that is more expensive. You might also look at PDFill http://www.pdfill.com/ Of course neither solutions is as convenient or as effective as being able to send annotatable and fill-able files to anyone with Adobe Reader. But this software may still be of interest. Elliot
