As someone who is a wp novice (less than 12 months using wp), I hope it's ok to pitch in from a newbie's perspective. I started with the 30-day free Lynda.com trial and used a lot of Morten's videos (several watched many, many times). These were a lifeline although finding the right tutorial at the right time was tricky and I came horribly unstuck with the wamp server tutorial at one point.

I've also used wp forums, theme forums, google searches and youtube. Mostly I've found what I need but often it's been a frustrating and long-winded process. That said, I've now set up 3 wp sites, all self-hosted and installed them from scratch. I've also learned how to set up a virtual host and migrate the data to/from the web (again, one horrific experience but thankfully I trialled it before any real data was lost).

Had I been able to afford it I would have gone to one of Mike Little's courses at MadLab (I live in Manchester). Unfortunately at £300 each it was out of my budget so I've been managing with videos.

Mostly I'm ok with tracking down something if I need it. My biggest frustration is out of date tutorials. I appreciate that this is partly due to the fast-moving environment that is wp but when you're viewing screenshots and they don't look like what's on your screen it can be pretty off-putting! Simply saying which version of the app/software/wp in the title of the video would be helpful in narrowing down a match to your version.

Of course, the other issue if you're not following a course (online, in person or otherwise) is that you don't know what you're missing if you don't know it exists (I suspect I have a few duplicated plugins, Jeff!).

Sorry, a long post but hopefully useful. Before I sign off though, I owe a huge debt of gratitude to all the amazing people who make videos/blogs/tutorials and who give their time to respond on forums, so thank you all!
