If you don't have a web login account yet, please register for a new one; within seconds you should receive an email with your password and be able to login to the web control panel from where you can create your DHIS hostnames.
Please note: Our policy for free dynamic DNS hosts requires that you must at least identify yourself with your real name and a valid email address. We are very strict about this and will lock any accounts that we find with fake names. Please try to be honest; we will not distribute your name or email address to anyone, but we do like to know that there is someone real on the other side and not a virtual troll.
