No need for rebooting
There is no need to reboot your computer after installing and configuring wicd. Arch != Windows so there's no need to reboot after installing some (trivial) stuff like wicd, If you want your new group for a user to be active you can just logout and login.

rc.d stop dhcpcd
Really? I'm gonna attempt to read through this and tidy it up a bit. Any obvious errors you see, please fix them. ;_;
