This is similar to Updating Questions After Receiving Answers but deals with a different sort of updating.
I asked this question Incorporating new people into a critique group
Last night, the new person attended her first meeting and has decided to join the group. I'd like to give a brief update as to how the advice I got worked.
- Should I do a horizontal line and then "update"?
- Should I put it in the comments?
- Should I allow the question to stand as is and not update it?
- Should I answer my own question, with the experience I now have? (though it's slight)
- Something else?
On a different SE, a questioner put an update in an answer, which was (rightly) deleted. I encouraged him to update the original question instead but, when he did, all or most of the update was edited out by mods. I don't know what the culture about updates is for Writing.
