It is a bit of an adventure to learn the culture of the different Stack Exchanges that I participate in.
Recently, I received a polite reprimand for the manner in which I formatted edits to a question. Upon seeing that, I hopped onto meta, read up on the matter, and consider myself informed.
What I don't know is: what is the most appropriate way to say, "Thanks. Got it. Won't do it again. Shall we remove this comment?" Or is it already the case that moderator comments such as this automatically disappear after a time?
