Help! How do I respond to replies to a question I posted? Can't find how to do it anywhere!

FYI there is no option to reply to individual comments in the discussions section. Generally I don't think it's necessary to reply separately to each person who comments, it's easier and the conversation often flows better if you just add any updates once in the thread for everyone to see.

You will see the reply, and just at the bottom of the reply is a little line" that says "reply to.......". Click on that, and a little box will pop up for you to type your response. It doesn't necessarily mean the person will come back to look again at that thread, so they may not see it, but you will have responded.
