"Opening a thread" you've started…How?

I was advised:

In order to put answers on your questions, just open the thread you have created and post a reply to that thread :slight_smile:


I can’t find how to do that. Please provide idiot-proof instructions. I can (a) send you a question (b) see the questions I’ve asked but no where can I see how to “open the thread” I have created.

Where on the dashboard (exact path please) do I go to find the thread and what magic opens it? Thanks.
