I've just installed wordpress 1.2 and I'd like to re-design the template, but I'm wary of working directly on the install. I figure I can install Php and Mysql on my desktop, but someone online mentioned the best method is setting up a test blog on Dreamhost. Do I need to set up a completely new domain, different than my real blog, or can I use a subdomain to set up a test blog?
After that, is it as simple as using the same MySql database with these instructions:
// Change the prefix if you want to have multiple blogs in a single database.
$table_prefix = 'wp_'; // example: 'wp_' or 'b2' or 'mylogin_'
Change 'wp_' to be anything else (because your first WordPress is already using 'wp_'). Maybe choose 'wp2_' for example!
Is this the best way to design your pages, considering that you need a server to see the pages as you work on them?
