Now I will be buggin' everyone here daily!
DON'T READ THE MANUAL... I've seen lots of people do this and getting really confused
Join a PSP group on the web. There are groups that have courses and or tutorials

Have fun and
Don't get addicted (too late, LOL)
Welcome to the land of addiction!
It is fun though.
