Apparently "Ignore User" is screwed up backwards...
The Old Way: If you chose to ignore a user, you wouldn't receive any PMs from them, but could obviously still read their public posts.
The New Way: If you chose to ignore a user, you can STILL get PMs from them*, but ALL their public posts are changed to "*** You are ignoring this user ***"
*An ignored user cannot
start a NEW PT with you, but they CAN
continue to PM you in an open PT, until you remove yourself from it.
The RIGHT Way: The
old way.

If someone's "earned" the right that you'd want to ignore them, you shouldn't be getting *any* PMs from them! Doesn't matter about their public posts, they can be ignored by skipping over them...
At the same time - When you "Remove Yourself" from the PM, it just deletes the entire exchange from your Messages. I think the PT should
remain, as a record, just be LOCKED until deleted manually.
PS - "Ignored" users still show up in the Shout Box.
