How would i

[Lovinmysailor]

Is it a paid membership or just like if you have certain amount of posts you get the platinum ranks?

If its a paid membership you could go through subscriptions and when they buy the subscriptions it will automatically put them in the user group of your choice thus changing the color. If it is for members with a certain number of post (or something like that) promotions would really be the easiest bet. You don't have to mess with anything once its done and you can input if its by their post count, rep point ect. If this is not what your looking for please explain. This is one of the areas of VB I am good at lol.
