Messed around with creating a new user (spidertest1), giving that user enhanced trust levels, letting the user start new threads and send PMs. Then I changed ownership of the thread created by the new user and deleted that new user to see how deleting the user would affect the threads originally created by that user. Also checked tried to look at the admin logs to see the treatment of the PMs created by the deleted user, but I’m not sure I looked in the right place. Anyway, anyone checking the admin activity will see me doing those things.
The reason for me doing this is that I wanted to confirm that I am able to delete user profiles without disrupting the site too much. I anticipate deleting user accounts on request, probably with some waiting/cooling off period, but retaining all threads created by those users by changing ownership of the original post.
Edit: since this is just a log, if people want to talk about the idea of account deletions, probably this thread is most appropriate for that discussion:
