I asked my first question over on a different SE site recently.
After an initial false start I was advised by a mod that when I edit my question to deal with comments, I can / should flag the comments as "no longer needed".
I've not come across this advice before. I've generally just left it to the commenter to delete.
Is this advice ubiquitous to SE, and is it welcome here on U&L? Or is this something mods here might see as a waste of their time.
