on a fairly large forum i'm on we have the ignore feature. we can put people who get on our nerves on there.
it's really nice. you don't have to read what they post (unless you are curious like me and peek) or someone quotes them.
gives you a bit of peace of mind.
oh and no one knows if they are put on ignore by another member.
actually, i only have one person on ignore on my soap forum. she knows that she's on ignore because i was ignoring her comments. and someone quoted her. so i told her exactly why i had her on ignore. fortunately for me, we don't have hardly any censoring on there so i got to tell her what i thought of her. it was lovely.
then i kept her on ignore
