Perhaps an Ignore button
i have not been a member long, and am aware that I have created ripples, and i see Debra has issues with someone, and so on. Regardless of post, I think I would read anyone's input, but that may not be for everyone.
What if Debra could just IGNORE bluewolf's posts, that is to say bluewolf would not show up on her screen. Others could put me on IGNORE, if they did not want to see or read my posts. To take it a step farther a moderator could simply count up the IGNORE's put on, and find truly disruptive members.
This last portion worries me a bit however, for I can see that being abused by groups of friends and such, but still it would allow the moderator an automated notice if someone is being ignored by 40 people or some such number.
