Thank you for replying. Surely, I got 2 emails from them, but it still doesn't clear my mind. I have simple questions, and want it to be answered.
Does Domain Registration ($9) itself allow me to upload any files on the DreamHost server? Other than transfering, and if I want to store files on DreamHost server, Do I need to sign up for web hosting plan (which costs 7 or 8 bucks per month?!).
I think I don't understand fundamentals of registeration and web hosting. I thought I just need to pay $9, get a domain, and upload files on that domain. If I am wrong, please tell me.
