I received notice in the mail that my domain registry for my website is due to expire in Feb. Is there a place I should renew this, or any suggestions on a good domain registry company?
You can renew with the same company who sent you the notice, or transfer to a cheaper service and renew with them.
One cheap service I just used is http://www.dotster.com.

another cheap site is www.godaddy.com
