Ok this is going to be my official slackware post. I used to think it had weaknesses as a distro compared to others like gentoo with its aptget and the *BSDs with thier ports collection, but lately I've been finding a huge slackware community out there and great tools.
For all of you who have had problems booting Slackware from CD on your old machines http://www.userlocal.com/dosslack/
A script to check and update all the packages in your slack install. Even the kernel (although that might be a little scarry) http://126.96.36.199/slackupdate/
The full gnome suite configured specifically for slackware. Installer and updater. Includes Xchat2 Evolution Gaim and Mozilla. http://www.dropline.net/gnome/download.php
Lots of great slackware info and community. http://www.userlocal.com
