Protonotes

I was just reading on the Adaptive Path Blog about a nice “sticky note” collaboration tool for designers.

“Protonotes are notes that you add to your prototype that allow project team members to discuss system functionality, design, and requirements directly on the prototype. You can think of it like a discussion board/wiki in direct context of your prototype.”

More from their site:

What's so great?

• Everyone on your team can easily add notes to your prototype - helps the entire team collaborate quicker and easier.
• Project team members don't have to install anything or sign up for anything to use it. It just works.
• It's not bloated with extra "features". It does one thing and one thing well - adds notes to your prototype.
• Works in all major browsers including Firefox, Safari, Internet Explorer, and Opera.
• Export your data at any time to a .csv file.
• Subscribe to your group's notes with a Protonotes RSS feed.
• Hook Protonotes up to your own MySQL database with a single line of JavaScript.
• It's free.
