I've been shipped off to a course in OCS2007. And it seems fun. First of all, a course like this is a nice break from the regular work schedule. Second, it is always nice to attend a course in something you're already somewhat familiar with. I have installed a few OCS's already, and know the basics. But at this course, you get to get under the hood. And get a finer understanding of the potential of this server product. Day 1 and day two are really basic. Setup, install and configure for simple use. But I am really looking forward to the next part: Conferencing with audio and video.
