Hello, There is actually quite a lot of difference between v2 and v5 ... enough so that if you wanted to take a class on it, Photoshop Elements targets photography enthusiasts and thus lacks many features that make it useful in a proper print production environment, it would probably be worth your money to also upgrade. If you want to go with the version that is on your computer, then look up tutorials online, originally introduced alongside Photoshop version 7, For example, Photoshop Elements cannot export files in the CMYK color mode, supports a simplified color management system, or go to the library and check out books on v2. As far as basic functionality, since you haven't even used the program, you probably could learn quite a bit working with v2 on your own and/or with a tutorial or book and excludes detailed soft-proofing some versions can, however, open, edit, and save PDFs.
