I saw a copy of it, no return address and it was not signed by the person or group of "concerend collectors" that supposedly sent it out.
It looks like they are trying to run down Dans reputation while at the same time they are hiding their own names. If they are so worried, why didn't they put their names on it before sending it out? I do not know if the lawsuit has merrit or not but some one is afraid to sign their name(s) to what they sent out.
