If you want to learn Acrobat quickly and easily you should check out Lynda.com, a service that offers online videos created by excellent teachers in a high-production format. You can try it for free for 7 days, and you should so that you can see for yourself why this service is amazing. They offer tutorials on every imaginable software, but let’s focus on Acrobat.
They have several tutorials on Acrobat (versions 9 and the new Acrobat X), and what’s great is that you can drill into a particular module that you’re interested in. Each module is about 3 to 5 minutes long, so you don’t have to get bogged down in an hour long session, which would be overwhelming and not conducive to learning. If you want to keep using Lynda.com it’s $25/month. Well worth it if you want to quickly (and easily!) improve your software skills.
