About the AuthorKarli Watson is a freelance writer, developer, and editor and also the technical director of 3form Ltd.(www.3form.net). He started out with the intention of becoming a world-famous nanotechnologist, soperhaps one day you might recognize his name as he receives a Nobel Prize. For now, however, Karlismain academic interest is the .NET Framework and all the boxes of tricks it contains. Karli is also asnowboarding enthusiast, loves cooking, spends far too much time playing Anarchy Online, and wisheshe had a cat. As yet, nobody has seen fit to publish Karlis first novel, but the rejection letters make anattractive pile. If he ever puts anything up there, you can visit Karli online at www.karliwatson.com.
