I was just collaborating with a few people from different agencies and we were on a conference call using /www.freeconferencecall.com/. It was an easy way to connect with a conversation and sharing the host's desktop.
I am always on the lookout for effective and efficient ways to share information and get feedback. This could be an option for topics that warrant more than an email, but maybe not a full leave-your-desk-and-drive-to-a-different-location meeting.
Let me know if anyone tries this and what you think!
