RoundCube offers a graphical and drag-and-drop interface. Log in using the same e-mail address and password that you use for POP3 or IMAP access.
Online password changing is temporarily unavailable, and will be back soon. In the mean time, please get in touch to accomplish this.
Connect to the web server using SFTP (conventional FTP is no longer available, as it's not a secure protocol).
To manage a domain name registration (e.g. the WHOIS details, such as administrative and technical contacts), use the OpenSRS domain manager.
Make a payment to Zygoat by one of several online methods, or by mailing a cheque.
