http://typetester.maratz.com/ - this is handy for choosing/comparing fonts, sizes, colors and background colors when doing layouts/design * for some reason it's not displaying in IE7 for me, but works in firefox.
http://www.xtort.net/scripts/scripts.php - this page has a large listing of online tools and generators for things like CSS layouts, flash, images, all kinds of stuff..some is just for fun, but quite a few webmaster tools here.
http://www.htmlbasix.com/disablehotlinking.shtml - will generate .htaccess code for you..its basic but will do the job for your average sites and you can always add code to it as/if you need.
