-You must log in to the forums (here) once a month to keep your account active.
-Remember when uploading files to put them in the public_html or www folders.
-Your account is subject to the TOS, which you have already agreed to by sigining up for a free hosting account. The TOS can be found here: http://x10hosting.com/tos.php

This is a good website for getting started with x10, and how to use some of the features offered here: www.stpvoice-x10support.co.cc
Thanks to Adam Parkzer for allowing me to redirect to his website
Another handy link...the server status page for all of x10's servers. Good to check if you think your site is down if the problem is server related. http://x10staff.co.cc/status/
