I see a lot of people asking questions and getting some pretty good responses, but the people who are responding, often do not get a thumbs up for their answer.
If you are new and you are reading this, then you maybe do not understand that a thumbs up actually helps the person who gave their time to answer your question.
There are several ways it helps, including giving feedback that the answer or the attempt to answer was actually useful, that you learned something or you appreciate the time it took to check your questions and give you feedback that you don't get in other forums, where you might be ignored for weeks or months.
This is a collaborative forum and we are all here to learn something and to pass some of our knowledge to others who need it.
Not every answer we give needs a thumbs up, but if you got something out of the answer, then, surely it is worth a second of your time to say "Thanks, that helped me" or "Yes, I agree with this"
