What would be nice to have is the ability to have a user promotion based on someone's registration date. I.e. the users registering before a certain date are "pioneers" or "early birds" etc.
I'd still like to see this. It would be a great and easy way to encourage people to sign up as early birds. Alternatively, if you could create a combination of "x" (number of posts, number of likes, profile comments, threads started, etc) and a date, it'd allow for an interesting way to encourage people to post more
