The Ignore List allows you to avoid seeing posts from people that you may not get along with or do not wish to read the contributions from.
You cannot ignore either the Administrators or any of the Moderators. You can't add yourself to your ignore list.
You can still send a receive pm's from people on your ignore list.
To add someone to your ignore list, do the following:
In a thread they have posted to Click <their username
Click <View Public Profile> from the drop-down menu
Click <Add their username
to Your Ignore List> on the mid-screen banner
Click <Submit> to confirm
A note will be inserted where these people post
To view the single post, Click <View Post>
To remove them from your ignore list, Click <Remove user from ignore list>
p.s. Sorry to pick on "Real" but I needed an example.
