To login to your ftp accounts you'll use the following information:
Servername: If the domain has propagated then you can use your domain name for the ftp server. If it hasn't, you can use the servername, your dedicated ip (for your main site only), or the server's IP if it's a shared account that does not have a dedicated IP.
Username: This is the same as your cpanel username for the account if you're attempting to log into the main ftp account. If you're trying to access a sub-ftp account (a ftp account you created through cpanel), then the username will resemble an e-mail address. For sub-ftp accounts, you will need to use username@yourdomain.com .
Password: This is either the password for your cpanel account if accessing your main account, or the password you set for the sub-ftp account if accessing a sub-ftp account.
Port: The port should default to 21, however if it doesn't, that's the port to use. Be sure to upload to the public_html directory too.
