I (and several others) tried in the past to get self-editing of posts allowed, with a short window of course. Some Staff and many posters all claimed the Earth would end if it was allowed.
However, editing has been around now for a while and the Earth (and the SDMB) is still here I see.
But seriously- how is it working? Any serious problems? Seems to have been OK by what I have seen, but I am not a Mod and don’t get complaints emailed to me. OTOH, I haven’t seen many PIT rants about some jerk who edited his post to make it say the opposite or anything.
