You probably know that we have an ignore function for ignoring other members used by editing your list in your User CP.
But did you know that you can also
ignore individual threads or forums?
To ignore a particular thread, click on the thread title, then the drop down menu at the top right of the first post that says "Thread tools", you can click "Ignore thread." It will no longer show up to you unless you un-ignore it in your User CP.
To ignore a forum, it works the same way except you click on a forum title such as "General Chat" and proceed as above.
