Hello guys,

i've created a patch for the Dynamic DNS client for IPFire. 
(http://git.ipfire.org/?p=oddments/ddns.git;a=summary)

My patch will add support for the very popular "dyndns.org" provider. 
However I wasn't able to test my changes, because
I don't have any account there and I seems new members have to purchase 
to use use it.

So, I need your help to test my changes and finally be able to support 
that provider in the next major version of IPFire.

Best regards,

Stefan
