Those of you who want to learn more about using Photoshop might want to look into a new course being offered by Matt Kloskowski at https://mattk.com/photoshop-how-to/. The course is on sale for $80 until Tuesday, the 6th.
I haven't reviewed this course, but Matt is my favorite online Photoshop and Lightroom teacher by far, so I'd be surprised if it's anything less than excellent. In any case, the course comes with a 30-day money back guarantee.
