I notice that if I pick up a typo or need to change a word immediately (i.e., within maybe 3 minutes) after I post something, I can do so and the resulting edited message does not show that it ever was edited. I think this is true even if somebody already has replied to the original message.
If I don’t notice the need for a change until, say, 20 minutes later and I edit it then, the edited message notes that it was edited and when.
How much time do I have to clean up a fresh post before it is actually marked as edited?
Also, it seems to me that if a long time (maybe a day, but I don’t know how long) passes before a message is edited, either this system or the old board also would request a justification for the edit. How does that work and what are the timeframes? Tnx.
