This unfortunately is a manual process, but works well once you understand it:

1) You need to access your text form linked to your domain.
    Go to this link: http://www.coza.net.za/Update_gen.php
    enter your domain name, eg mydomain.co.za
2) A text form will appear, copy this entire form.
3) Paste it into your notepad text editor .. NOT MSWORD!!!
4) Update the form, its self explanatory.
5) For the nameserver change to IDS Hosting see text below:

6a. Primary server FQDN: ns1.idshosting.co.za (contact us for the correct nameservers)
6b. Primary server IPv4 glue:
6c. Primary server IPv6 glue:

6e. Secondary server FQDN: ns2.idshosting.co.za (contact us for the correct nameservers)
6f. Secondary server IPv4 glue:
6g. Secondary server IPv6 glue:

Fill in the red only under 6a and 6e

6) Copy the entire form and paste it into a new email
7) Set email to Plain Text , goto Format, select Plain text.
8) Send to: coza-admin@co.za

You should get a resonse in about 15 minutes to tell you if there is a problem or the information has been updated.
