Here is what i'm thinking... you are a domain reseller, right? WHy didnt you pick up something which would hint at the fact that you sell domains or that people can register domains on your site. Nobody will type in 'global' if they are looking to register a 'domain'. Second, why not a .com or a .net at least. Your primary aim is at the .com .net.org domains, right? At least you list those first (although i saw the sale marked on biz). As the domain name, global.biz does not stir any feelings in me. I dont feel like it belongs on a domain registration website. As for the domain registration website itself, you used the tucows apis, right? Change the graphics, change the layout (i can do it for you) and get people to register with you. The website then will pull in some resale value.
Just my 2c. I dont mean to be rude, i am just trying to explain why i give it a $15 the way it is right now. WIth another line of business, i would have rated it higher (in the $300 range), but dont listen to me, you know better what your plans are.
I would strip the content and pick a domain-related name. I would then market Global.biz as something else or stipped as a plain domain name. That could net you good cash - $300-400 for the domain.
Good luck and if you need the website designed, drop me a line.
