Strangely enough, the fine people at Envato thought the world would benefit from jQuery as well and have offered up a free course: Learn jQuery in 30 Days. On the sign up page, it reads:
Each day you’ll be sent a free video lesson. At the end of the month, you’ll be able to confidently use jQuery in your projects, without help.
So. I’ve signed up, let’s see if I’m confident with jQuery in 30 days! :D
