Note: I didn't downvote! (yet)
Earlier today, I flagged an answer as it really wasn't an answer at the time. However, the poster later added a JSFiddle example (which didn't really answer the question either but merely repeated the OP's post) but it got a few comments going, and got the OP engaged, which resulted in some useful comments before the answerer bowed out. The OP also commented via their own comments and on other posts.
It is the habit of this particular user, s/he should have used the comments IMHO to extract the extra info needed or make their original observation in the first place, and I shouldn't have been so quick off the mark with a flag! I'm not worried about the wrong flag but what if anything should or can be done in a situation similar to this.
I know it was likely a "FGITW" type answer, where a user was hoping to edit (may still happen) but again IMO it failed this time. If it was me who'd tried it, I would delete but then I wouldn't want to delete what may be useful comments = hence the quandary and my question.
Is there anything that can be done to either retract the flag or explain why the flag in the first place (beyond the original not an answer!)?
My apologies to whoever saw my flag!
