Glad you asked, I just changed mine and wish everyone would.

Place your arrow over the "YOUR HOUZZ" in the upper right hand corner. When drop box appears, click on edit profile. below you name and other info is a box with your name as the public see it. Click on that area and change it. Hope this helps

Thank you, will try.

didn't work

yes it worked...thanks again!

Someone who works at Houzz commented on another thread that if you put zone info in the zone box, it only shows up on the GW threads, but if you put it as part of your name it shows up on all the threads whether GW or Houzz.
