I have just added a new screencast to the site. This one shows how to add and use a PoodLL countdown timer to a Moodle activity.
The previous screencasts have been a little quirky with the sound messing up on occasion and getting out of time with the video. So I have started using the online screencast-o-matic service, and that is so much better.
I have also modified the way we embed videos so that ipod/iphone and ipad users can see the videos too.
Anyway the screencast is here. I hope you enjoy it.
