RE:IGNOREIt is not so easy, you actually have to click on one of their posts.
Here is how I do it:
Go to:
https://www.stockhouse.com/members/notwrong
Name of whomever you are ignoring goes where he is shall not be named is.
Scroll down to "My Bullboard Posts" and click on one of them.
You will then see:
This is a hidden post by a user from your ignored users list: notwrong.
Under this you will have the option to unignore the user in question.
Hope this helps.
