If you ask a question in the Q&A section, you can look there for the question and the responses. If you ask a question on your own page (the "How was your day" post or as part of Your Story) then you should be able to find any responses on your page. The problem comes when you ask a question in response to someone else's post or on the comments to an article. Then it will get completely lost unless you happen to remember who you were responding to.

OK Thanks again,Dale.. I'll look in the archives. It was probably a like or a hug response..

Thank you,Dale.. I received your notfication and your response.. But sometimes I get a notification and no response.. Thats when I look for my sent message to see if anyone responded to it.. Then I can't find my sent message..

Sometimes the response is a like or a hug. Sometimes it’s buried in a long line of other responses.

If someone responded to your question you should receive a notification to that effect.
