The problem with writing complete 'How to's' for editing is it can become very involved and needs often to be interspersed with screesnhots of PS or PSP to mean anything to a complete newcomer, so it can be a major undertaking. Then we use terms like Mask and Layer which often don't mean a thing to the newcomer either.
I think once you've got a good grasp of what a Mask is (Called a Selection in PSP) then you're well on the way to being able to tackle most things.
