Please tell me how to enable Wildcard DNS on my server for only one domain?! This is the requirements from here: To install and run BlogHoster, you will need: 1. PHP 4.2.0 or newer installed 2. An available MySQL database 3. FTP access to your server For the randomly-generated image verification feature to work (optional feature), you will need: 1. GD Libraries 2.0 or newer installed, and accessible with PHP For the subdirectory-style weblog URLs feature to work (optional feature), you will need: 1. The ability to use .htaccess files (usually requires that your server is running Apache) 2. mod_rewrite enabled (default for most Apache servers) For the subdomain-style weblog URLs feature to work (optional feature), you will also need: 1. Wildcard DNS setup on your server.
