I for one allow unlimited editing -- (still running the old Classic board, getting ready to move to Threads).

It has never been much of a problem. One old timer got fussy about his number of posts, and went back and deleted many that he thought were useless. That was no problem.

In another case, a troublemaker started a thread, then deleted his first post, removing all followups. But this guy was removed some time later.

I would like to see some way to allow unlimited editing in Threads. what is the highest number allowed in the setting?
