I religiously use emails everyday. Some of the emails are really hard for me to reply. So I decide to make a chart below and I will put this on my homepage after adding more instructions.

One more thing: Please do not write to my co-authors of the same paper separately. This will make each of them spend 15 minutes to reply the same set of questions. Put them all together in To'' field.

And, please read How to ask questions The smart way'' before emailing me. http://catb.org/esr/faqs/smart-questions.html

This chart is made out of Open Source software only.
