Change Style trough Promotion

[jluerken]

Hi,

I created two forum designs. One is very basic for all the guys which are new to my board. The second has a lot more information and options and looks very overloaded if youre new to the system.

Therefore I want to have all users with less X posts to see the default "light" style.
After writing their X+1th post they should get a promotion.

This promotion should not switch them to another usergroup
but change their design to the overloaded version

Is there a way I can do so?

kind regards
