I've taken a bunch of HP online courses that are free and they are great! I don't think you have to have an HP product to take them. The most recent one I took was (I think 6 classes) Adobe Photoshop class. If you're interested click on the link below and I believe the Adobe classes are under digital photography. There are 6 basic classes and then there are a group of advnaced classes. Some of the classes are only offered a limited time. The Adobe class is until July 22nd so don't put it off! They also have; Tune up Your PC, Computer Basics, Security Boot Camp, Firewalls and others. Check it out! You even get a certificate of completion when you're done!
