I asked this question -> goo.gl/jKh2fd and now would like to expand it to include a related question that user VL-80 asked in the comments. Is that okay? .. How should I go about it. Also, I want to change the picture to annotate the related question. Just wondering if this would cause confusion when someone else reads the question and answers later
@VAN You should ask a new question. "Changing your question after you've received answers is inappropriate, as it invalidates the answers you've received. It can even make those answers wrong, and adversely affect the reputation of those who answered. If you now have a new or additional question, create a new post and ask it there; you can link back to the other one if needed for reference."
DavidPostill is right. I'd rather not make edits that could invalidate existing answers. If you have a new question that builds upon an existing question, it's best to post it separately.
Didn't feel like steeling another user's interesting question. Instead asked the other user to ask it separately so that it gets the attention it deserves instead of getting lost in comments. Thanks guys.
