username changes color according to posts

[EmmaB]

What do I do to get the usernames to change color according to the number of posts a member has made? i.e A member makes 25 posts their username is blue and then when they hit 50 posts it changes to green?

You would have to make separate copies of the Registered User usergroup making each rank group with a different color and then run a script so when they hit 50, they will move onto next group and so on.
