Not trying to interfere, yet I found the topic multiple times in the resource videos.
Like an example "
What is a Joomla Wrapper? " at approx. 1 minutes and 55 secs.(more specifically 2m55secs...or even better, 6 minutes and 12 seconds,
Explained it well for me, especially if one has used sample data to actually see it work" on a local host(design setup).
Be patient, I been banging my head on joomla/code for a long time, and I must say, this is the best, quickest, easiest tutorial / application I have seen to streamline the whole process. I wish I had half the head knowledge Brian has and I can't wait for the 3.0 to be complete. Rock on Dude!! and Thanks x 2!! ( I meant no sarcasm in this post either, just trying to help..)
P.S. there is another at 8min 39 secs......same video,
