Clicking the “Create” button when submitting a new post results in some form of status message. Maybe it says “Your post has been submitted”. Maybe it says something about adding tags. Maybe it says something about duplicate posts.
… How about making that status message more visible? Maybe add it somewhere… I don’t know… even close to the button used to submit the post? Currently, the window just scrolls up slightly and it’s hidden in a sea of other text using the same font/color. Super easy to miss if you rarely have time to use the forums.
