So I appreciate the people that share their JavaScript work out there, because it gave me a place to start when I was stuck on a problem! But, ya know, even though nothing ever fits perfectly, it really sucks when you get bad tips - and there are a lot of "plageristic" web sites that scrape stuff from other sites and then bulk up their sites with a bunch of crap.

The stuff that follows is real stuff I use every day that works.
