Skype is great.

And you can often find contacts (a target JV partner) on there by searching by name. You may get 2-3 results... just toss a feeler to each of them and you'll end up on Skype directly with the person you want to deal with.

Skype is a must in my world. Only surefire way to reach me. I take sabbatical's from my email inbox, Facebook PMs are never treated with priority, my personal cell phone is turned off when I'm focused and working, office line never gets answered... but skype is great.
