You can email me, Rosana Hart, at rosana, then the at sign (@), then hartworks dot com. (My email is listed that way because humans can understand it but mechanical spam-harvesters can’t.)
Sometimes I am traveling and sometimes my Mexican internet connection gives me a few problems, but normally I answer my emails pretty quickly. Feel free to re-send if you don’t hear from me within a few days. Not all emails that are sent through cyberspace actually reach their destinations, sometimes due to sturdy s p a m filters.
