Yes it is, i have contacted them. And for assurance, you dont directly get it from me, you directly get it from hostagator. THey said:- Send us the domain that needs to be setup as master domain. Then u sign up as usual from hostgator. And they will credit ur account with 6 months hosting.
I have stuck up deal with rojar123 to take over this 6 month host plan.. and am now in the process of finalizing this deal. I have sent a PM to you rojar with the signup domain name.. Thanks, Boulder
