When you put on ignore their post still shows up in the window containing all the posts. However, a diagbal small window is added between where your PICTYRE, ETC. ARE, AND JUST BEFORE THE GREEN reply AND new messages. in front of it there is a red buttionn and a note telling you you have that user on ignore. At the end of that informative line there is a note saying "click here" to unignore that person...

Hope this helps...
