You could also setup a SUBdomain on your account usualy for free

For example:

My site is: ragecgi.com

And a month before I found SM, I was going to start my own tut site at:
anger.ragecgi.com ...sortof a play on the word rage


Best part is that is was free for me to do this as much as I wanted, but your hosting package might be different.
