The updated version has some new tools and a great deal more detail.
Something I use a lot. I should explain my requirements – I often answer students’ questions on mathematics on our school VLE. Now writing mathematics can be a pain (and yes I know about LaTex), all I want to do is to be able to communicate quickly. An online whiteboard which can be saved is perfect – I just post the link to our student forums, these have been very well received. Note that a graphics tablet is essential.
Now I am wondering which is best for my use….
An interesting tool – screenr seems to do exactly what I want, it is very easy to use and plays back as I want it to – send straight to your chosen application or get the url (or both). screenr test 2. The screencast can be published easily to YouTube. Update: You can now sign in to screenr in a variety of ways (formerly just Twitter). For a training video on using Screenr – see this by Russell Stannard. (From his Teacher Training videos site).

twiddla – good in that we can all use but files cannot be saved – good for collaboration.
Scriblink – this seems to work well, files can be saved, an email (which takes rather too long to arrive) provides the link.
Another to try: Board 800
Update – August 2011 – another easy way to have a quick scribble – Doodle.ly see quadratic example. Select Doodle Now, doodle, then publish; I used my Twitter account, other options are available including Facebook.
