[Plugin: bbPress] Getting control of the edit log

I’ve got a couple of posts that received a few edits and the displayed log in the posts looks pretty bad. I’ve looked through the database, but can’t find where the edit log is kept (I intend just to delete the extras that don’t have any value)

Also, the checkbox for “Keep a log of this edit” is marked by default. Is there a way to have it unchecked by default? The default setting is part of the problem why my edit logs look so bad.
