PPl should send letters, It does not matter. You feel you are doing your part.
You feel empowered.
JMW does not read every letter and committed it to memory. She likely read them as group of concerned investors who could not make the trip to her courtroom. But, wanted to let the HER know their feelings.
And by extension, a poorly written is the same well written letter. My guess is that there have been 2500 letters sent to her. Since all letters are from viewed as pro se, they are given certain leeways in proper format and legal documentation.
Again, I'll say it again: Be Proactive. I was saying this long before ER. She does not know YOU are live unless you send her a letter.
The other reason is Rosenusuck and all other lawyers have to know what is in your letter just in case.
