www.POWRHOST.com offers unlimited free hosting for WordPress and other apps. Free cPanel, free scripts, free auto-install.
Update 14.02.2012
I just learned the hard way that each 30 days of “inactivity”, the Powrhost system auto-deletes your entire blog and contents. You’ll get an email that your “free account” has been “cancelled” for “inactivity”. You will login to your basic account, and find you can re-activate the extra free accounts they deleted, but you have to start all over, re-instal wordpress, re-upload your theme, ec. NB – URGENT for you to always DOWNLOAD a backup of each blog’s contents after each time you work on it, and keep your THEME handy, so you can restore most of it in a crisis.
