kup and tober..no worries
another call to the rescue....
jay, click on User CP, look down the menu under Miscellaneous > Buddy / Ignore List and click on that
There are two frames
1. Buddy List
2. Ignore List
You just have to type the initial or some of the person's nick e.g. Ice and then the system will auto-find a match and you can click 'Enter' on your keyboard, followed by clicking 'Save List' button.
Person to be ignored e.g. Iceburn's posting will be ignored in all threads...
