When I register domains at godaddy, I then change my nameservers to my host. After that, I use Fantastico to install wordpress. Well, I did that right after i purchased the domain, and the domain still says its under godaddy. Usually when I do this right after I purchase the domain, it works instantly. Do you think I just have to wait a while, and then it will show up? Please let me know. Thanks for your help!
Are you on Windows? If so start up a command prompt and type in "ipconfig /flushdns". On Vista you'll have to run it as an administrator. If you're using a router, reboot it, then try to visit the site again. If it still doesn't work, you'll most likely have to wait for your ISP to get the right nameservers.
