The Jing Project by TechSmith (one of my favorite software creators, makers of SnagIt, which I don't have any desire to live without), is utterly amazing. Until I found, viewed, and understood it yesterday, it took a long time, a lot of effort, and a significant amount of frustration and disk space to display a short "how-to" video of a process which I might need to "show" users how to do.
This is how it works: Go to Jing and download the program (about 5 MBs). Install it and notice the icon that appears in your system tray. Right click that little baby and choose "Capture," drag a box around the area you want to capture--generally, the size of the largest window that you need people to see. To record a video (which is the most amazing thing), just click "Video" and start clicking (and talking if you have a microphone). When you finish, hit the stop button, then choose the "embed" option. After you sign in and wait a few seconds, the embed code will be sent to your computer's clipboard. All you have to do then is paste the html code into your web page. Don't worry a bit if you know nothing about code. It doesn't matter! It will work anyway! Check out this tiny example and imagine the POWER of this tool!
To Jing, in the words of the immortal Shakespeare: "Thanks and Thanks and Ever Thanks."
