A while ago I heard about TinyUrl.com and thought it was a pretty neat utility for shortening URL's to paste into emails or other documents. This helps to avoid those really long links that often get broken due to word wraps in emails. More recently I found SnipUrl.com and it is even cooler. It will keep a catalogue of URLs you have snipped so you can use it as a reference. You can also assign your own nickname to the shortened Url so the new link can have some descriptive quality instead a collection of random numbers and letters.
JING is a really cool (FREE) utility from TechSmith that will capture snapshots from your computer screen or record video (and audio) from your screen. If a picture is worth 1,000 words - what is a video worth? JING will output your capture to a local file, an FTP server or to screencast.com, their free hosting service. I did a little sample screen recording that you can see from the free hosted site here - http://screencast.com/t/pw9TwhVUXc. Techsmith is the company that makes a really cool (not free) screen capture program called SnagIT that I probably use every day.
