how can i see what questions someone done from my accunt Q&A if someone used my profile?

If you go to your profile, you'll see the topics you have opened, and if they are still, "Under Moderation" then they have not been addressed. Though if there is no mark next to the topic, it has been published. And lastly, if there is the mark, "Answered", then the answer has been pinned to the top of the topic as the answer.
