The Flat Classroom projects have run a series of Free Tools Boot Camps in Elluminate/Black Board Collaborate and saved the recordings as a resource for others. You can find all the recordings and lots of other great resources on the Flat Classroom Project Help Wiki. I have also linked to the most relevant videos below:

Skype groups, such as "Hello Little World Skypers" and "Global Classroom" are an ideal way to connect with educators around the world, discuss ideas for projects, and arrange skype conferences between educators, and between classrooms around the world. These groups are built around a pubic IM (text) conversation, which any group member can read & contribute to, in a similar fashion to an email discussion list.
