Skrbl.com - Online Whiteboard for Work or Play

Give Skrbl points for creativity. Every school and office has a whiteboard for sharing, collaborating and brainstorming on ideas and projects. This is the online version of the whiteboard, which literally allows you to write, draw, and erase anything and everything you want; you can even draw over another person"s work....just like the real live one. You can have a public or private whiteboard, and can put up text, photos, or files. To start, you sign up and start drawing. Then you can share your URL with others by email to allow them to share the site or to just look at it. The site touts the ability to have projects and meetings sketched out and changed easily through the whiteboard, or you can "graffiti" with a small or large community and let the creativity flow with anyone else in your community.
