Can't wait for antiX 15 to come out of beta phase so that i can install it to my USB drive. Does anyone know of a tutorial about installing antix onto a usb drive? Or can i just use Unetbootin to install it to my usb drive?

You can use Unetbootin to install to usb. It will be running 'live' though, is that is what you want?

I made a live USB and installed antiX as a regular install to another USB. I just started the install process from the live USB and selected the second USB as the device to install to. Both this process and the USB install work very well.
