Hi ya, I've been away for a while, also.
I believe IAAL, through his attorney, agreed to a Restraining Order to cease all contact with Free Advice. The initial pleadings by FA are within the above banner.
IAAL was posting at Expertlaw (& raising a bit of heat) for a short period after he left FA, then, I believe he disappeared. As far as I know, he was never identified.
There were a few threads, here, talking about IAAL after he left; I don't know if they were deleted since. He created a very diverse reaction to his posts/personality.
