Since there has been a rash of inappropriate threads/posts, I wanted to answer this out in the open for all to see, instead of answering the question in the original thread. No need to keep drawing attention to that thread and behavior.
If there is someone posting things that you do not want to see, then go to that person's profile page, 3rd line down under his image will read: Add to Ignore List. Click that link which will direct you to a new page asking confirmation. After clicking yes, then you will no longer see their posts. I just wish it would void out their thread titles as well.
