How to mockup a website if you're not a designer

I spent eons searching for an answer to this question and finally a friend tipped me off to the best way to mockup a web page without using a heavy design program like Illustrator, Photoshop or Fireworks (or even the old fashioned pen and paper method). First, the SnagIt extension for Firefox is an easy way to capture bits and pieces of other sites you wish to emulate or show the designer. Next, these can be very easily pasted into good 'ole Powerpoint, which is an easy way to organize multiple screens. Powerpoint allows you to insert all sorts of useful shapes and buttons, as well as text boxes which can be used to annotate. So far this system seems to be working well. Hopefully this blog post can save someone else the time it took me to figure it out!
