One thing that I like to do in my spare time on the internet is find and do Photoshop tutorials by other people on the internet. One of the best places i've found is Good Tutorials.
This site is a collection of user submitted tutorials, that are some of the best around. Each tutorial which is submitted goes through a moderation stage of 5-7 members. As a result each tutorial is top quality and you don't get the spam ones falling through. I really like it. Many of my tutorials can be found on the site. So check it out.
