i just saw this post. i have been ill. at first when i saw this, forgot what it was about, but here is what was done:
no, nothing i have done warrants a lawsuit. they attacked through the internet and notified yahoo that i was answering dental questions and that i was wrong and that biologic dentistry is quackary designed to take people's money. they told them that cavitations do not exist, etc.... this person (and his dentists friends) send me emails saying all this and more and said they would destroy me. they said they were contacting yahoo to get rid of me. so, yahoo took everything i had to do with my yahoo account. when i called yahoo, they said they will not reinstate and i would need a court order to pursue anything. get this, they suggested that i just create a new yahoo id! so i did. but i lost a lot of important info.
