Adobe Connect
Adobe Connect is one of the most intuitive and reliable online instruction and conferencing software that is available. In January of 2010, I collaborate with three other librarians to develop and present instruction on using Adobe Connect to all instruction librarians at the University of Wisconsin.
The software is also widely-used throughout the University of Wisconsin School of Education. In the Fall of 2010, I developed a workshop for users of the software and have since consulted with several instructors as they design courses using Adobe Connect.
The documentation and handout for the workshop are here.
Here is an example of Adobe Connect:
