Skype conversations can be a pleasant way to brainstorm and learn more about one another on a personal level. But for discussing the details of your project, email is much better, for many reasons:

• The information is saved online, and serves as a valuable record of our discussion.
• Email messages can be searched and referenced at any time in the future, so we do not have to rely upon our memories.
• Any messages can be resent if necessary.
• Both parties can take all the time and space they want, to be exact in describing questions and answers. When you express what you want in your own words in an email message, it reduces the potential for misunderstandings.
• Project requests conveyed in a phone conversation can be (unintentionally) vague, which causes frustration and wastes valuable time. In contrast, email messages encourage us to be more specific.
• Everyone has the information they need to do their tasks, which saves time and reduces the chances of miscommunication.
• Files and website addresses can be easily sent via email.
• Email is convenient for both of us, allowing us to send and receive messages whenever we want, day or night. It is not intrusive or interrupt what we are doing, as does a phone call. We can receive and send information at our convenience, not dictated by a ringing telephone.
• Because I spend my productive time at my computer, it is easier to read and respond to an email as soon as it is received.
• Email is free, unlike any phone call outside of our area codes.
• I do not have a phone, because I do not want anyone disrupting my personal life or inadvertently treating me as an on-call employee.
• I'm more productive with no phone, being able to concentrate on work, since writing code requires uninterrupted focusing.
• Contacting me via email is just as fast and reliable as using a phone, because I'm at my computer for most of the day, and I am immediately alerted to any new messages.
