As we know that LeetCode doesn't provide us any way to view all our posts, I have figured out an easy method to keep track of our posts.

1. Go to the "My list" section
   

2. Over there create a new List called Posts
   

3. Then open the question which you have written a post for and hover over "Add to List" ,click on Posts and then click on Done
   

4. Now you can keep track of all the posts by going to "My List" and opening the discussion section for the question you have added in the list.
   

5. In the discussion section just search for your username and you'll be able to see your post.
