Hi Moosa,
Thanks for your true advise. We are still debating should we remove the hyphen on the domain name. One of our concern is the hyphen on the domain may affect SEO or Link Building, but we have no way to proof at this moment.
And we have read lots of articles, but still do not have conclusion. We are actually looking to redesign our e-commerce store and change to a better platform. After that we will run some online PR campaign, linking building and SEO works. So we have to decide weather we should keep the hyphen or should we remove the hyphen.
