This site is powered by WordPress, an amazing [wikipop]Open Source[/wikipop] [wikipop]blog[/wikipop] and [wikipop]Content Management System[/wikipop] (CMS) program. WordPress is the same software used to run WordPress.com and Edublogs, along with thousands of other blogs/websites. I use Coda for coding/FTP and host this site with bluehost.com.
You can setup your own wordpress site at either of the two websites listed above or download WordPress and use it on your own [wikipop]webhost[/wikipop]/server. Bluehost is $6.95/month for unlimited storage and file transfer and includes one free [wikipop]domain name[/wikipop] for life ($10/year). If you are a non-profit Dreamhost.com offers free hosting and a free domain name!
