Comment preview is back!
After a long hiatus and due to popular request, comment preview has returned to help in your quest to create nicely formatted comments and walkthroughs. Just click the "Preview" button below the text input field in the comment form to see a preview of how your comment will appear when posted, spoiler tags and all!
If you encounter any trouble with the feature, please let me know. Use the email address in the sidebar if you need to.
