Can anyone tell me how to pay to my web hosting company?
With check or credit card?

. . . biting my tongue. . .

I recommend paying by credit card, this is fastest and easiest method available. Also you have some insurance from your credit card company.

Remember, both can be a nightmare if you choose a "bad" hosting company.

I advise you to use your credit card. If somethings goes wrong, you can always file a chargeback on your credit card company and you will get a full refund.
