I am very new to servers and domains, etc, so please forgive the following ignorance:
I have hosting through ServInt as well as several domains. A few domains are through GoDaddy and some others through 1&1. One of my GoDaddy domains is set up already (don't ask me how - someone did it for me). I need to forward the other 2 GoDaddy domains to the one that is set up or at least link them all to the same content. I currently upload files to this site using the Transmit FTP client. I also have access to this site's CPanel. What is the process for directing the other 2 domains to the working one?
Also, I have 2 domains with 1&1 that I want to link together in the same way, but neither one is set up with nameservers/CPanel/FTP. I'm not sure how to connect these domain to ServInt hosting (I know it involves nameservers/DNS) but it's over my head. What is the process for creating CPanel and web access for a new domain and establishing FTP?
Thank you in advance
