Am I the only one that doesn't know how to use photoshop? I feel so inferior.

Learn Photoshop:

To learn the basics of Photoshop, I recommend this video tutorial from PSD Tuts+. This course on UX Foundations is another good resource. However, the best way to learn is by doing and PSD FanExtra has written a great blog post featuring step-by-step tutorials on how to create everything from an online portfolio to a corporate website.

It can also be a good idea to review lessons 26-30 of 30 Days to Learn HTML and CSS by Tuts+ which teaches you how to splice a Photoshop file and turn it into a live site.

Lastly, there is HackDesign, a new Codecademy-esque design course that launched last month (previously covered on TechCrunch here).

I found that here:

And that's why I forced myself to learn. I wanted make stupid things.

You can also use Photoshop professionally, you know.
