Very good question, for me the best way is to use skype with voice or with text chat. if a person doesn't have skype, no problem, you can use or an email or a private message on sfi or other chat client. once or twice at week for me is a good time, but if you have some questions to do, it's so much better conctact psa/csa daily. the same strategy can be used to contact sponsor and cosponsor.
