I signed up for (ordered) webhosting from webhostinghub.com a few hours ago, and when I did so, I clicked "install WordPress" under "Auto Install one of these CMS products?" on the order form. I get "Server not found" when I try to type in my url for Word Press administration too. From your answer above, should I be expecting to wait up to 24 hours to be able to access it? Also, will the login details be sent to me by e-mail? I'm told to expect such an e-mail here: http://howtostartablogonline.net/
This is the site where I learned about your service.
Yes, the initial domain propagation can take up to 24 hours. You also should have received a Welcome Email from us at the email address you used to set up your account. If you chose the option to install WordPress you should see your WordPress login information in that Welcome Email.
