Thanks for the response. If you don't find the resources useful or relevant, it seems to me that it would be better to reply with your reasoning and links to other resources. Or are you using "downvote" to mean "I disagree"?
I can't downvote yet so I'm not one of those who did - I was trying to give an explanation. I don't know the exact rules for downvoting but I assume some use it to say " not helpful".
