This place is like the Hotel California. You can check out anytime you like, but you can never leave.
And why are you laboring under the misapprehension that all your posts and all of the posts of people who replied to you will be deleted if you get the zot? Jim told you that would not/could not happen.
BZ asked Jim to leave her threads up, so that content by other FReepers wouldn’t be lost. Jim told her that he can’t delete all of her posts without deleting all the threads she started, and he said he’s not going to ask John to write a program to make that possible. Jim has given BZ 10 days, and she’s using that time to notify FReepers that if they wish to save the content they’ve contributed, they need to do it now. Some of them have put a lot of work into their research.
