Taking a class

I'm so excited about the class Adobe Photoshop Elements 13: Essentials I with the Pixeladies! It's online and started this Monday and it will last for three weeks, then I'll take Essentials II. I've just finished my third lesson "Straighten Images". I used one of my photos and with a couple of "clicks" it turned out much better.
No need to tell before and after, is it? Next will be to create a watermark.
