IGNORE - how to find out
Go to the top right of this page and click on example: 65 members / 56 guests
Then look at the left column, almost to the bottom and you will see how many people you have on ignore as well as the number of people who have you on ignore. When you click onto "You are ignoring" , you can see who you have on ignore. I don't know if the same is true when you click on "You are ignored by" because I don't see that anyone has me on ignore. So try it and see if you find a board where someone has you on ignore.
Also, you have to do this for each individual board you post on. Hope this helps.
