We have all of these archived askJTF's. All the info is there
There's no question that the JTF Archives that WestCoastJTF put together would provide more than enough for an excellent biography about Chaim.
Having said that, I hope that one or more people who have copies of the JTF programs from the 1990's emerge and provide Chaim with those programs. The predictions that Chaim and his co-hosts likely made on those programs could provide invaluable to effectively promoting JTF.
Also, the guest appearances that Chaim made on programs during his days in the JDL would prove invaluable as well if someone has those programs.
What I suggest is that a permanent sticky thread is made in the general section of the English Forum mentioning that if anyone has copies of any programs prior to the time that WestCoastJTF was able to provide JTF Archived programs, they should contact Chaim. With a link to the JTF Archive site, which would indicate which programs JTF already has in it's archives. This way, new members to the forum would be aware of the need for these past programs that JTF currently doesn't have access to.
