You should never really trust a company whose primary business is registering domain names. Companies like Network Solutions, Register.com, and GoDaddy come to mind. Avoid them. We use Joker or 1&1, although I would never ever recommend the latter for hosting or anything like that.
Thing is, we have a client who has set up an extra domain that isn’t going to be working for a few weeks. In the meantime, I wanted to just point the new name to the old host, or something like that. Register.com will do this, but they force a banner ad to show up for the rest of the site visit! If you want the ad to go away, they charge an extra $50. This, on top of their already high prices.
Maybe that’s what you have to do to stay in business as a Domain Registrar. If so, that’s not a business I would want to be in. I’m not used to such dealings, I’m used to paying a flat rate and being able to do what I want with my domain names.
