I found a useful link from DesignBump with a list of cheat-sheets for WordPress. Some of the cheat-sheets are new to me but others I use and have been an asset for creating my personal blog theme. I’m new to WordPress but it’s not so hard to grasp and with these resources it’s even easier.  One resource that should be included in the list is “Huge Compilation of WordPress Code” from WP Hacks. Very useful with a wealth of information.
