How can i check for answer to question i asked plus how can i reply to question that was the same as mine

Hi! Whenever someone replies to your post, you will be sent an email by default. If you’re not receiving emails from Apple Support Community, you should check your preferences:

1. Click your profile picture at the top right of the website > Preferences
2. Check which of the boxes are checked under “Messages from Apple”
3. If you want to receive an email every time someone responds, check the “Participation” box

To reply to someone else’s post, just click the “Reply” button underneath, type your response and click “Post”.

Feel free to try it out with my reply! ☺️

Click on your username. Select "View Profile" to get this page:

Then click "Subscriptions" to get this page:

Use the filter options I highlighted with the red box to change between Following, Participated, or Authored.
