I came across this very functional tool recently and I
love it. It's easy to use and a wonderful way of talking to your clients,
students, etc.whenever you cannot meet them face to face or online. It's like
Camtasia, IMHO, with the added value that you can be recorded while you make
your presentation thus adding a bit of a personal touch!? You can get a free
account, but from what I understand you wound't be able to have many
presentations up unless you get a plan :-(. They also use the same referral
system Dropbox uses so there is a chance of getting more 'storage' e.g.
presentation space. All the same, I think the fact that you can add
yourself to the presentation reduces the distance and detached feeling one may
get if only listening to the presentation. If you want to try it out here's the
