Hostgator shared hosting plan upgrade from single domain to multidomain
 

I have a hostgator hatchling plan which can support only one domain. I am using wordpress for my website. Now I want to host another domain using hostgator hostings. Should I upgrade to Baby plan (Multidomain ) or go for a new hatchling plan (single domain ).

you buy godaddy host . very good

You can upgrade your plan or purchase an addon domain. You better ask hostgator about this issue
