Sage has created a channel on YouTube where they have started posting videos. At this time, there are some nice case-study and user interviews.
I’m not sure what the plans are for this channel, but hopefully they’ll add more product demonstration and basic training videos like the ones I linked in this previous blog post - Free ACT! by Sage video training.
For now, have a look at these: http://www.youtube.com/user/ACTbySAGE
