The best website tool that I have used it HTML-kit. I use it when I write php and html. It's the best free html editor that I have found on the internet. I know it has nothing with the abowe stuff to do, but it's a usefull tool
I also liked bravenet once, but I also got a lot of spam a short time after joining. I don't know what's wrong. I guess they sell the e-mail lists to spammers.
Another greate website for web-tools and resources is
Hotscripts.com :: The net's largest PHP, CGI, Perl, JavaScript and ASP script collection and resource web portal
It's the biggest database of scripts on the net.
