Hello Annie, I just edited my most recent post. If you pull up your homework thread, you should see some “shadow” text at the upper right corner of your post–on the right side of the gray bar. “Edit” should be there. The text is slightly darker gray, designed to be visually unintrusive; it’s possible you’ll have to adjust the brightness of your monitor to see it easily. I know my eyes don’t discriminate grays and blacks in dim light as well as they used to!
Just click on “Edit” and you should then be able to modify and resubmit your post.
