You can give them a Thumbs up or just include "Thank you to all who respond" at the end of the details section of your question. You could also comment under their answer, but if they don't come back to the question and look at it, they won't know you commented.

You can give your feedback by clicking on the "comment" at the bottom of each answer. Just be careful not to click the flag next to it
