Dabbleboard is another online whiteboard application for collaboration on the web. Dabbleboard is simple and has all the essential features for a whiteboard.
Unlike other whiteboards like Scriblink it auto corrects your drawings, it detects common shapes and transforms in to a smooth shape. Apart from that you can add shapes, pictures, text and freehand drawing.
While you are drawing you can share your whiteboard with others for collaborating, so that both of you can write on the board. You can also choose to make your board public or private, share with only your invitees.
It is free to use, you can start your whiteboard instantly, but if you want to save you need to register.
I’d also like to mention my personal side project, Fooboard. While it may not be completely finished (yet) and lacks some of the super-advanced features found on other boards, it’s very easy to use and has a familiar interface. If you can use Office, you can use Fooboard!
Please, if you try out my board, leave feedback. I need to know what people want!
