I have the same problem with ISPconfig3 I can't add my:
To my godaddy account (domain register) it says: they are not registerd? While my www.donotarguehostedservers.com
both seem to be working?
Any help regarding DNS would be nice as all documentation on ISPC3 or this whole site are unavailable, incomplete or there's just no documentation at all (one of the biggest negative points @ ISPC3 and it's developers, write some friggin documentation already, if you can code a whole app why not make note's allong the way?)
