For wordpress you need access to a database - right? (wordpress.com does not give access to plugins etc so not counting that). Are there any hosting sites that let you put up a wordpress site for free?
Its just that I have a few domain names I'd like to develop....
Your best bet is just a general free PHP/MySQL host. WordPress.com and other sites running WordPress mu (multi-user) don't let you do that sort of thing. You could try HostGator's 1 cent "trial" month too, which is about as close to free as you can get. There are some coupons for this floating around the net.
Don't bother with free hosting - you get what you pay for... not much. Splurge a few dollars - you can get shared hosting for as little as $5 a month. While shared hosting can be sketchy depending on the company you deal with it's still a far sight better than any free host for what you need.
Dreamhost and Hostgator for example have one-click installs of wordpress. It couldn't be much easier than that.
Frihost is the only decent " free host " you can find around these days. Even its not really free. you have to post in their forum in return. still it worths.
