Backboard

Backboard is a new Web 2.0 utility that allows a user to get feedback on whatever project they might be working on. Managers can get input on product plans, Web designers can get input on their proposal, students can get feedback on their class projects...

Backboard is a free online tool that allows feedback solicitation on the most common office documents, images, web pages, URL's and free-form text. Once you've loaded your project, a form pops up to invite users to review and provide input, or you can invite them through your own email to your Backboard URL.

At this time, you cannot edit the project in Backboard. If edits are required, you simply upload the newest draft and resolicit input.

A great time saver for reviewing documents, reports etc but I feel that it could do some with markup tools which allow WYSIWYG editing.
