For all you windows users trying to organize and edit your photos... I suggest Picasa (by google). It's easy to learn and after just a few clicks you can do things that I are buried under three separate menus in photoshop. Check out this example... a blurry shot I took just after the big group pic. Well after a pushing a few buttons and moving some sliders around it became my new background. I'm actually posting this picture using Picasa (you can also use it to upload pics to flickr). Anyhoo, just a quick .nerd post.
Ever heard of sketch up? That might be my next .nerd post.
