The obvious choice is email. Check out my email address at my department employees pages. If you want to talk to me, Skype is a good option. My Skype id are available on request (use email). I am also available on iChat/AIM (id = mac.com account, available on request), Google talk (id = gmail account, available on request), and maybe MSN Messenger (id available on request).

Old traditional phone and mail (snail mail) is also an option. My current address (69º39'32"N,18º56'29"E) and phone numbers are:
