To clear the record, not all "Free Domains" are registered or controlled by the hosting company. Most hosts register these "free domains" in the name of the hosting company, not the name of the customer.

Its basically another way these guys like to "stick it" to their loyal customers.

GlowHost offers free domains, however we do it differently. We register them in the customer's name, not ours. Here is a useful FAQ:
