LOL Oh trust me they are out there, that is the users and the tutorials alike!!
I don't really know where to start explaining PSP Tools do, I learned PSP all on my own by reading throught thousands of tuts and trying everything I could. I love to push buttons and see what happens!!

There are very few tutorials out their yet for PSPX, but most all of the tuts all the way back to Version 6 will work in PSPX, with your knowledge of PSP you can usually easily find your way of converting them with the new tools in PSPX.
Yes sadly tutorial site come and go constantly, they are either under a new name or have just been lost forever!
I never run out of tutorials for PSP by doing a search on google, we also have a lot of threads here in the PSP forum that have many links to PSP tutorials.
My favorite site of course is psplinks.com, if you notice the whole list on the left hand side it will take you to I would guess 1000's of different sites that have PSP knowledge!!
Another thing is you can go to the Corel site and look for a link to newsgroups and find the one for PSPX, subscribe to it and right there you have the real PSP Pros right at your finger tips!! LOL I am in there also, not saying I am one of the Pro's at all, but they have taught me sssoooo much!!
