How do I ignore another user or why does someone not respond when im talking to him/her?
If there is any repulsive chatter in the room, simply select his screen name in the user-list and click “Block” from the menu on the left. The screen name will then turn red. Every message the chatter posts to you, whether private or public, will not appear on your screen. If you change your mind, you can select this user and click “Unblock” to disable the ignore feature. If you continued to post message to someone but got no response, you probably is ignored by him or her, that means you had better watch your behaviours and words.
