V.K.,
Wanna know what's nifty? OK, open Text Edit. Start typing email addresses; for purposes of demonstration, just make up a bunch of nonsense email addresses, but formatted properly (whosit@anywhere.com). Here's the catch: Type them with no spaces, but separated by by commas (whosit@anywhere.com,jane@doe.net,etc.@blah.org).
When you think you have typed enough, select all the text, then drag it out to your Desktop.
Now, I'm sure you're aware of how we can drag any text out of just about any application to get "text clippings." As it turns out, Leopard's Finder combines this tech with the newer "data detectors," and Voila!!, we get instant email lists!
Try it out. Once you have dragged that clipping out of Text Edit, quit it (don't bother saving the document, just the clipping). Instead of a normal clipping, it becomes a "Mailto" file (with a ".mailoc" extension). Double click it. Pick up your jaw, and close your mouth, V.K.
