Okay, I logged on to manage my domains and there are all kinds of things to fill in.
Where can I go for clear instructions on:
1. setting up my domain for hosting (already registered on DH)?
2. setting up email accounts for that domain?
3. anything else I need to know for getting things set up?
I'm just finishing up the web site itself using xSitePro.
Thanks for pointing me in the right direction.
