. . . why does it say ignore this member on the post board. did do something wrong, or register wrong . .
You didn't do anything wrong. That little "iggy" button is on everyone's address block. If someone is bugging you, and you don't want to read what they say, you click on that, and their posts don't show up.

Don't click on your own though. I have no idea what happens if you ignore yourself . . .
