If you want to stop receiving messages from another user, either because you don't find them interesting or for any other reason, you can add that user to your ignore list. Once you have done that, you will no longer see any of the user's public or private messages. The ignore list is a chat feature and only applies to messages specifically. You will still be able to see any and all comments, ideas or scripts by users on your ignore list.
Please note the following:
You can easily ignore any user by right-clicking the user and selecting Ignore from the context menu.
In case you change your mind and want to be able to see someone´s messages again, you can open your ignore list, find the name and delete it from the list.
