Though I'm sure there is more extensive support for Photoshop, there is plenty for Paint Shop Pro also.
Here are two newsgroups:
comp.graphics.apps.paint-shop-pro
alt.binaries.paint-shop-pro
Here's an online PSP Users Group:

Here's where the Users Group lists their Forums:

Here's a link to Amazon's PSP 7.0 Anniversary Editon for $36.99 with rebates:
Paint Shop Pro Anniversary Edition
If you do a search in your favorite search engine on Paint Shop Pro Tutorial and Paint Shop Pro Forum, you'll find many online resources.
After you get your program, go to the Jasc web site and download the update patches:

One thing you'll love about PSP is the image browser. Following is a screen shot of it. On the left are your folders and on the right are the images in your folder. If you hold the mouse over an image, the information about it pops up without opening the image (see the gray box on right).
