It often happens that people contact me for information and after I write a response...sometimes a lengthy response...my email comes back undeliverable.
This is to let you know that I respond personally to every email unless it is obvious that someone is just using me solely for their own benefit (and even then I sometimes respond). So if you do not receive a response, please check the email address you gave me. For example I just sent a reply to shyam.nagarajan but it will not send.
