Added a fun mod this morning. At the bottom of the
forum home page, there's a section for User Spotlight. It changes every day, and chooses a random user based on a few parameters (50 minimum posts, logged in within the past month, and posted within the past two months). If you have a profile pic, it will display that. If you only have an avatar pic, it will display that. It will not choose any user that doesn't have at least one of those pic areas loaded.
EDIT 9/13/2015: Widened the pool a bit by changing some parameters: Minimum posts are now 25, users need to have logged in within past 2 months, posted within past 4 months, and users who have not customized their avatar or profile pic are now eligible.
