Subject: Re: Clearing the Board for May
A technical point regarding my proposed solution: I understand if person B replies immediatedly to a post from person A, and A deletes his post after 10min this could be confusing, kind of "What is B replying to?".

This could be remedied similar to the grey "...faint murmuring in the distance" you see instead of the post of an poster you put on "Ignore": By replacing the deleted post with a grey "...it was there, and now it´s gone", making clear what's happened --- plus reminding A himself on not being too spontaneous, so that Manlobbi´s psychological intention is still fulfilled.
