The 'Markup Reminder' link which sometimes appears under Related Recipes does not open in a new window. Perhaps this is considered good style, but regardless of that debate, it is unconventional when compared to many wikis which open markup/formatting help in a new window. Furthermore, opening in the same window on some browsers will cause any existing form data to be discarded when pressing 'Back' after reading the markup help. Therefore if this behaviour is kept, there should at least be a tooltip warning which says 'Opens in the current window'.
