I am still learning myself, and have only touched the surface of what Sonar can do; for me, when I come across a problem/question, I search here at the forum or on Google, as the Cakewalk search function is somewhat limited.
Just open a Google search and enter the following:
"site:forum.cakewalk.com" -plus your search terms (e.g., how to edit clip automation)
Also, I've created an archive of forum threads too. Every time I run across a thread with answers I'm looking for, I save the page as a pdf file into specific folder on my hard drive (e.g., automation, mixing, plug ins ... you get the picture) so I have easy access in the future. You can archive Youtube videos also if you have a program to download streaming vids (I use YTD Video Downloader--it's gratis)
Salud!
P.S. Other good youtube sites are Andrew Byrne and David Valles channels
