You can edit your own post for up to 60 minutes after posting it. 

NOTE: The reason why we have this limitation is to enable to you move on. Too often, English learners get bogged down by their perfectionism. 


Click on the text that says "Edit" at the bottom of the post you want to modify, and you'll be taken back to the editor where you can make changes before submitting the post again. 

If you do not see "Edit" under your post, that means you can no longer make changes to it as the 60 minutes buffer period has passed. Don't worry :) if there's something important you want to add, create another post in the same discussion (as a reply) & give us the update.
