You're welcome all!

Ivan, we think alike - am planning to disect a few juicy default materials after folks understand a bit more. Also want to encourage everyone to read the Function Editor stuff in the manual (maybe i'll put that in the opening still shot).

Surveyman:
Thanks, as for the audio, i'm maxed out, but will try to find another 3-6 dB somewhere. Since no one else has complained about the audio level from my several video clips, i thought it was okay, despite the Camtasia audio track looking pretty anemic. On the other hand, don't want to blast people and make them reach for the volume control.

What do the rest of you think - need more audio level?

Advertise my eBook in the video? Why didn't i think of that! Maybe another still at the end? However hyperlinks are a bit hard to do and slow the video creation/publishing process - worth it i guess. And i could add a 'Back' button to the video HTML page a the same time - though those will force vertical scrollbars for many.

Will try to get another Function Editor video clip out every few days, until i've reached my limit of understanding.

Cheers!
