So is that the purpose of being able to have so many parked domains (I see this advertised all over as a hosting benefit) - just to be able to own all the extensions without using up your account space?

I've used it for shortened email addresses - which is very effective for long domain names, to have a second domain which is abbreviated for ease of use.

I thought there was some SEO benefit to having parked domains...guess I will have to research that a bit.

Thanks for the responses!
