Links
Here are some links I think many of you will find quite useful.
Arch Linux Official Website
Arch Linux's offical website where you can find news and updates about Arch Linux.
Arch Linux User Repositories
In the AUR, you will probably find many packages that aren't available in the official repos. The most popular packages get put into the community repo, saving you a bit of time compiling.
Arch Linux Forums
Arch Linux's official forums where you can get support for Arch Linux. It's also a great place to chat.
Official KDE Website
My favourite desktop environment is KDE and highly recommend people to use it. But I'm not stopping you from choosing something else like Gnome, Xfce or one of the plentiful window managers (Openbox, Fluxbox, Ratpoison, Awesome etc.) out there.
Ubuntu Forums
A great place to chat, or get help with any of the Ubuntu derivatives (based on Ubuntu). I used to use Ubuntu but the forums are great so I just keep coming back 
Drupal
Archux is powered by a great open source content management system (CMS) called Drupal. I highly recommend people to use it for websites.
Dreamhost
We are hosted by Dreamhost, and they are great! I recommend them if you are looking for website hosting.
