i'm a newbie and i have a free wordpress.com host (iskoblog.wordpress.com). now i want to move this to my own hosting. i was able to install wordpress and transfer all of my few posts there but one thing i didn't consider: domain. for my own host it's now something like http://myserver.com/~username/wordpress/
so is there any way to get my own hosted blog to have adress like iskoblog.wordpress.com or something else or do i just have to go shopping for a domain?
