I think @k00b already has it in the works, but a little nudge won't hurt. I have been pushing for this for a while. I'm just worried that allowing perpetual edits on discussion posts could really mess up the back and forth talk between stackers. I pushed for a special type of index post, to be applied to posts like those great table posts that you made. There has been a lot of back and forth, so I think they have taken everything into consideration
